The authors conducted a systematic review and meta-analysis of randomized controlled trials to determine if placement of a drain after a colonic or rectal anastomosis can reduce the rate of complications. METHODS: A search of the Medline database of English-language articles published from 1987 to 1997 was conducted using the terms "colon," "rectum," "postoperative complications," "surgical anastomosis," and "drainage." A manual search was also conducted. Four randomized controlled trials, including a total of 414 patients, were identified that compared the routine use of drainage of colonic and/or rectal anastomoses to no drainage. Two reviewers assessed the trials independently. Trial quality was critically appraised using a previously published scale, and data on mortality, clinical and radiologic anastomotic leakage rate, wound infection rate, and major complication rate were extracted. RESULTS: The overall quality of the studies was poor. Use of a drain did not significantly affect the rate of any of the outcomes examined, although the power of this analysis to exclude any difference was low. Comparison of pooled results revealed an odds ratio for clinical leak of 1.5 favoring the control (no drain) group. Of the 20 observed leaks among all four studies that occurred in a patient with a drain in place, in only one case (5%) did pus or enteric content actually appear in the effluent of the existing drain. CONCLUSIONS: Any significant benefit of routine drainage of colon and rectal anastomoses in reducing the rate of anastomotic leakage or other surgical complications can be excluded with more confidence based on pooled data than by the individual trials alone. Additional well-designed randomized controlled trials would further reinforce this conclusion.  (+info)

The effect of chronic coffee drinking on blood pressure: a meta-analysis of controlled clinical trials. (2/12901)

We sought to assess the effect of coffee consumption on blood pressure in humans. Our data sources included a MEDLINE search of the literature published before December 1997, bibliography review, and expert consultation. We selected controlled trials in which coffee consumption was the only difference between the intervention and control groups, mean blood pressure change was reported for each group or period, and treatment lasted for >24 hours. Of 36 studies initially identified, 11 (522 participants) met these inclusion criteria. Information on sample size, study design, participant characteristics (gender, race, age, baseline blood pressure, and antihypertensive medications), and treatment results were abstracted by 3 reviewers using a standardized protocol. Treatment effect of coffee consumption on blood pressure was estimated with the use of a random-effects model. In the 11 trials, median duration was 56 days (range, 14 to 79 days), and median dose of coffee was 5 cups/d. Systolic and diastolic blood pressure increased by 2.4 (range, 1.0 to 3.7) mm Hg and 1.2 (range, 0.4 to 2.1) mm Hg, respectively, with coffee treatment compared with control. Multiple linear regression analysis identified an independent, positive relationship between cups of coffee consumed and subsequent change in systolic blood pressure, independent of age of study participants and study design characteristics. The effect of coffee drinking on systolic and diastolic blood pressure was greater in trials with younger participants. Our findings provide support for a relationship between coffee consumption and higher blood pressure. Trials of coffee cessation of longer duration and in persons with hypertension should be performed.  (+info)

One-year survival among patients with acute myocardial infarction complicated by cardiogenic shock, and its relation to early revascularization: results from the GUSTO-I trial. (3/12901)

BACKGROUND: Although 30-day survival is increased in patients with acute myocardial infarction complicated by cardiogenic shock who undergo coronary revascularization, the longer-term outcome in such patients and the duration of benefit from revascularization are unknown. METHODS AND RESULTS: We analyzed 30-day survivors of acute myocardial infarction in the Global Utilization of Streptokinase and Tissue-Plasminogen Activator for Occluded Coronary Arteries (GUSTO-I) trial and identified 36 333 who had not had cardiogenic shock (systolic blood pressure <90 mm Hg for >/=1 hour, group 1) and 1321 patients who had shock (group 2). Group 2 patients were older and sicker. At 1 year, 97.4% of group 1 patients were alive versus 88.0% of group 2 (P=0.0001). Among group 2 patients, 578 (44%) had undergone revascularization within 30 days (group 2A) and 728 (56%) had not (group 2B). Revascularization was not required by protocol but was selected by the attending physicians. At 1 year, 91.7% of group 2A patients were alive versus 85.3% of group 2B (P=0.0003). With the use of multivariable logistic regression analysis to adjust for differences in baseline characteristics of shock patients alive at 30 days, revascularization within 30 days was independently associated with reduced 1-year mortality (odds ratio 0.6, [95% confidence interval 0.4, 0.9], P=0.007). CONCLUSIONS: Most patients (88%) with acute myocardial infarction complicated by cardiogenic shock who are alive at 30 days survived at least 1 year. Shock patients who underwent revascularization within 30 days had improved survival at 1 year compared with shock patients who did not receive revascularization, even after adjustment for differences in baseline characteristics between the 2 groups.  (+info)

Racial differences in the outcome of left ventricular dysfunction. (4/12901)

BACKGROUND: Population-based studies have found that black patients with congestive heart failure have a higher mortality rate than whites with the same condition. This finding has been attributed to differences in the severity, causes, and management of heart failure, the prevalence of coexisting conditions, and socioeconomic factors. Although these factors probably account for some of the higher mortality due to congestive heart failure among blacks, we hypothesized that racial differences in the natural history of left ventricular dysfunction might also have a role. METHODS: Using data from the Studies of Left Ventricular Dysfunction (SOLVD) prevention and treatment trials, in which all patients received standardized therapy and follow-up, we conducted a retrospective analysis of the outcomes of asymptomatic and symptomatic left ventricular systolic dysfunction among black and white participants. The mean (+/-SD) follow-up was 34.2+/-14.0 months in the prevention trial and 32.3+/-14.8 months in the treatment trial among the black and white participants. RESULTS: The overall mortality rates in the prevention trial were 8.1 per 100 person-years for blacks and 5.1 per 100 person years for whites. In the treatment trial, the rates were 16.7 per 100 person-years and 13.4 per 100 person-years, respectively. After adjustment for age, coexisting conditions, severity and causes of heart failure, and use of medications, blacks had a higher risk of death from all causes in both the SOLVD prevention trial (relative risk, 1.36; 95 percent confidence interval, 1.06 to 1.74; P=0.02) and the treatment trial (relative risk, 1.25; 95 percent confidence interval, 1.04 to 1.50; P=0.02). In both trials blacks were also at higher risk for death due to pump failure and for the combined end point of death from any cause or hospitalization for heart failure, our two predefined indicators of the progression of left ventricular systolic dysfunction. CONCLUSIONS: Blacks with mild-to-moderate left ventricular systolic dysfunction appear to be at higher risk for progression of heart failure and death from any cause than similarly treated whites. These results suggest that there may be racial differences in the outcome of asymptomatic and symptomatic left ventricular systolic dysfunction.  (+info)

Safety of long-term therapy with ciprofloxacin: data analysis of controlled clinical trials and review. (5/12901)

We reviewed the literature and the manufacturer's U.S. clinical data pool for safety data on long-term administration of ciprofloxacin (Bayer, West Haven, CT). Only controlled clinical trials including patients treated for >30 days were selected. We identified 636 patients by literature search and 413 patients in the Bayer U.S. database who fulfilled our search criteria; the average treatment duration for these patients was 130 and 80 days, respectively. Main indications for long-term therapy were osteomyelitis, skin and soft-tissue infection, prophylaxis for urinary tract infection, mycobacterial infections, and inflammatory bowel disease. Adverse events, premature discontinuation of therapy, and deaths occurred at a similar frequency in both treatment arms. Most adverse events occurred early during therapy with little increase in frequency over time. As with short-term therapy, gastrointestinal events were more frequent than central nervous system or skin reactions, but pseudomembranous colitis was not observed. No previously unknown adverse events were noted. We conclude that ciprofloxacin is tolerated as well as other antibiotics when extended courses of therapy are required.  (+info)

Separate and joint effects of micronutrient deficiencies on linear growth. (6/12901)

Recent studies have investigated the effect of micronutrient deficiencies on growth stunting, with special attention toward the effect of zinc, iron, vitamin A and iodine deficiencies. In Mexico, the prevalence of growth stunting in children <5 y old is approximately 24%; it is higher in rural areas and lower in urban areas. In an initial study, the effect of zinc and/or iron supplementation on linear growth was investigated in a longitudinal, placebo-controlled design. After 12 mo of supplementation, there was no difference between the groups supplemented with zinc, iron or zinc plus iron and the placebo group. At baseline, 82% of the children in this study were deficient in at least two out of the five micronutrients that were determined, and 73% were anemic. In another study, a mixture of those micronutrients that were documented to be lacking in Mexican children was formulated in a supplement and given to Mexican children over a period of 12 mo in a longitudinal, placebo-controlled, supplementation design. Children in the low and medium socioeconomic status grew about 1 cm more than similar children in the placebo group. This difference was not found in children of high socioeconomic status. It is suggested that, in most cases, growth stunting is associated with marginal deficiencies of several micronutrients and that in populations with multiple micronutrient deficiencies, the effect on linear growth of supplementation with single nutrients will not be significant. Supplementation with multiple micronutrients is expected to be more effective, but even in that case the actual increment in height was less than the expected potential increment.  (+info)

Colorectal cancer mortality: effectiveness of biennial screening for fecal occult blood. (7/12901)

BACKGROUND: In 1993, a randomized controlled trial in Minnesota showed, after 13 years of follow-up, that annual fecal occult blood testing was effective in reducing colorectal cancer mortality by at least 33%. Biennial screening (i.e., every 2 years) resulted in only a 6% mortality reduction. Two European trials (in England and in Denmark) subsequently showed statistically significant 15% and 18% mortality reductions with biennial screening. Herein, we provide updated results-through 18 years of follow-up--from the Minnesota trial that address the apparent inconsistent findings among the trials regarding biennial screening. METHODS: From 1976 through 1977, a total of 46551 study subjects, aged 50-80 years, were recruited and randomly assigned to an annual screen, a biennial screen, or a control group. A screen consisted of six guaiac-impregnated fecal occult blood tests (Hemoccult) prepared in pairs from each of three consecutive fecal samples. Participants with at least one of the six tests that were positive were invited for a diagnostic examination that included colonoscopy. All participants were followed annually to ascertain incident colorectal cancers and deaths. RESULTS: The numbers of deaths from all causes were similar among the three study groups. Cumulative 18-year colorectal cancer mortality was 33% lower in the annual group than in the control group (rate ratio, 0.67; 95% confidence interval [CI] = 0.51-0.83). The biennial group had a 21% lower colorectal cancer mortality rate than the control group (rate ratio, 0.79; 95% CI = 0.62-0.97). A marked reduction was also noted in the incidence of Dukes' stage D cancers in both screened groups in comparison with the control group. CONCLUSION: The results from this study, together with the other two published randomized trials of fecal occult blood screening, are consistent in demonstrating a substantial, statistically significant reduction in colorectal cancer mortality from biennial screening.  (+info)

Report of a National Institutes of Health--Centers for Disease Control and Prevention workshop on the feasibility of conducting a randomized clinical trial to estimate the long-term health effects of intentional weight loss in obese persons. (8/12901)

A workshop was convened in 1997 by the National Institutes of Health and the Centers for Disease Control and Prevention to consider the need for and feasibility of conducting a randomized clinical trial to estimate the long-term health effects of intentional weight loss in obese persons. Although the benefits of weight loss in obese individuals may seem obvious, little information is available showing that intentional weight loss improves long-term health outcomes. Observational studies may be unable to provide convincing answers about the magnitude and direction of the health effects of intentional weight loss. Workshop participants agreed that a well-designed randomized clinical trial could answer several questions necessary for developing a rational clinical and public health policy for treating obesity. Such information will ultimately provide needed guidance on the risks and benefits of weight loss to health care providers and payers, as well as to millions of obese Americans.  (+info)

As reported by Hope S. Rugo, MD, and John W. Park, MD, both of the University of California, San Francisco, and colleagues in The New England Journal of Medicine, the multiarm adaptive randomization phase II I-SPY 2 trial has shown that the addition of veliparib/carboplatin and the addition of neratinib to standard neoadjuvant therapy have met criteria predictive of success in a phase III trial of the same comparators in early breast cancer patients with specific biomarker signatures.1,2. I-SPY 2 Details. In the I-SPY 2 trial, multi-arm adaptive randomization is being used to evaluate the effectiveness of multiple new agents added to standard neoadjuvant chemotherapy in producing pathologic complete response in high-risk stage II to III breast cancer based on biomarker subtypes. The aim of the multi-arm adaptive randomization scheme is to more rapidly and accurately identify experimental regimens with a higher likelihood of success in phase II trials that can include smaller numbers of ...
BACKGROUND: Adults in intensive care units (ICUs) often suffer from a lack of sleep or frequent sleep disruptions. Non-pharmacological interventions can improve the duration and quality of sleep and decrease the risk of sleep disturbance, delirium, post-traumatic stress disorder (PTSD), and the length of stay in the ICU. However, there is no clear evidence of the effectiveness and harms of different non-pharmacological interventions for sleep promotion in adults admitted to the ICU. OBJECTIVES: To assess the efficacy of non-pharmacological interventions for sleep promotion in critically ill adults in the ICU.To establish whether non-pharmacological interventions are safe and clinically effective in improving sleep quality and reducing length of ICU stay in critically ill adults.To establish whether non-pharmacological interventions are cost effective. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL, 2014, Issue 6), MEDLINE (OVID, 1950 to June 2014), EMBASE ...
© 2017 Tucker et al. Background: Self-monitoring of blood pressure (BP) appears to reduce BP in hypertension but important questions remain regarding effective implementation and which groups may benefit most. This individual patient data (IPD) meta-analysis was performed to better understand the effectiveness of BP self-monitoring to lower BP and control hypertension. Methods and findings: Medline, Embase, and the Cochrane Library were searched for randomised trials comparing self-monitoring to no self-monitoring in hypertensive patients (June 2016). Two reviewers independently assessed articles for eligibility and the authors of eligible trials were approached requesting IPD. Of 2,846 articles in the initial search, 36 were eligible. IPD were provided from 25 trials, including 1 unpublished study. Data for the primary outcomes-change in mean clinic or ambulatory BP and proportion controlled below target at 12 months-were available from 15/19 possible studies (7,138/8,292 [86%] of randomised
Introduction: Self-monitoring of blood pressure is effective in reducing blood pressure in hypertension. However previous meta-analyses have shown a considerable amount of heterogeneity between studies, only part of which can be accounted for by meta-regression. This may be due to differences in design, recruited populations, intervention components or results among patient subgroups. To further investigate these differences, an individual patient data (IPD) meta-analysis of self-monitoring of blood pressure will be performed. Methods and analysis: We will identify randomised trials that have compared patients with hypertension who are self-monitoring blood pressure with those who are not and invite trialists to provide IPD including clinic and/or ambulatory systolic and diastolic blood pressure at baseline and all follow-up points where both intervention and control groups were measured. Other data requested will include measurement methodology, length of followup, cointerventions, baseline demographic
Although the effects of physical fitness training on death, dependence, and disability after stroke are unclear, there is sufficient evidence to incorporate cardiorespiratory training that involves walking within poststroke rehabilitation programs to improve speed, tolerance, and independence during walking, say authors of a meta-analysis published in November in the Cochrane Database of Systematic Reviews. The authors searched the Cochrane Stroke Group Trials Register, the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, SPORTDiscus, and 5 additional databases. They also searched ongoing trials registers, handsearched relevant journals and conference proceedings, screened reference lists, and contacted experts in the field.. Selection criteria included randomized trials comparing either cardiorespiratory training or resistance training, or both, with no intervention, a nonexercise intervention, or usual care in stroke survivors. Two review authors independently selected ...
Granulocyte colony stimulating factor (G-CSF) may enhance recovery from stroke through neuroprotective mechanisms if administered early, or neurorepair if given later. Several small trials suggest administration is safe but effects on efficacy are unclear. We searched for randomised controlled trials (RCT) assessing G-CSF in patients with hyperacute, acute, subacute or chronic stroke, and asked Investigators to share individual patient data on baseline characteristics, stroke severity and type, end-of trial modified Rankin Scale (mRS), Barthel Index, haematological parameters, serious adverse events and death. Multiple variable analyses were adjusted for age, sex, baseline severity and time-to-treatment. Individual patient data were obtained for 6 of 10 RCTs comprising 196 stroke patients (116 G-CSF, 80 placebo), mean age 67.1 (SD 12.9), 92% ischaemic, median NIHSS 10 (IQR 5-15), randomised 11 days (interquartile range IQR 4-238) post ictus; data from three commercial trials were not shared. ...
Objectives: To assess the accuracy in diagnosing heart failure of clinical features and potential primary care investigations, and to perform a decision analysis to test the impact of plausible diagnostic strategies on costs and diagnostic yield in the UK health-care setting. Data sources: MEDLINE and CINAHL were searched from inception to 7 July 2006. Grey literature databases and conference proceedings were searched and authors of relevant studies contacted for data that could not be extracted from the published papers. Review methods: A systematic review of the clinical evidence was carried out according to standard methods. Individual patient data (IPD) analysis was performed on nine studies, and a logistic regression model to predict heart failure was developed on one of the data sets and validated on the other data sets. Cost-effectiveness modelling was based on a decision tree that compared different plausible investigation strategies. Results: Dyspnoea was the only symptom or sign with high
BACKGROUND: Randomized trials without reported adequate allocation concealment have been shown to overestimate the benefit of experimental interventions. We investigated the robustness of conclusions drawn from meta-analyses to exclusion of such trials. MATERIAL: Random sample of 38 reviews from The Cochrane Library 2003, issue 2 and 32 other reviews from PubMed accessed in 2002. Eligible reviews presented a binary effect estimate from a meta-analysis of randomized controlled trials as the first statistically significant result that supported a conclusion in favour of one of the interventions. METHODS: We assessed the methods sections of the trials in each included meta-analysis for adequacy of allocation concealment. We replicated each meta-analysis using the authors methods but included only trials that had adequate allocation concealment. Conclusions were defined as not supported if our result was not statistically significant. RESULTS: Thirty-four of the 70 meta-analyses contained a mixture of

Our present results are similar to the latest Cochrane review by Cooney et al, 24 who found a moderate effect of exercise on depressive symptoms (−0.62 SMD) when including all trials and no effect when restricting the analysis to trials with less risk of bias (−0.18 SMD). The Cochrane review did find evidence of a small antidepressant effect beyond the intervention, which we could not confirm in our present systematic review. Bridle et al 13 included nine trials allocating old (,60 years) participants with depression to exercise interventions versus control interventions. Restricting the analysis to four trials at lower risk of bias they found small-to-moderate effect estimates (SMD −0.34) in favour of exercise. The studies by Cooney et al 24 and Bridle et al 13 both included trials allocating participants with depressive symptoms and not necessarily diagnosed using a validated diagnostic system, potentially explaining the differences in the effect sizes. However, in our present systematic ...
The role of N-acetylcysteine (NAC) in the treatment of chronic bronchitis is unclear. Since a number of studies have been published on this topic, a systematic review of published studies seems justified. A systematic search (Medline, Embase, Cochrane Library, bibliographies, no language restriction) for published randomized trials comparing oral NAC with placebo in patients with chronic bronchitis was performed. Dichotomous data on prevention of exacerbation, improvement of symptoms and adverse effects were extracted from original reports. The relative benefit and number-needed-to-treat were calculated for both individual trials and combined data. Thirty-nine trials were retrieved; eleven (2,011 analysed patients), published 1976-1994, were regarded as relevant and valid according to preset criteria. In nine studies, 351 of 723 (48.5%) patients receiving NAC had no exacerbation compared with 229 of 733 (31.2%) patients receiving placebo (relative benefit 1.56 (95% confidence interval (CI) ...
Many key RCT methods were not used or not reported. Adequate allocation concealment, adequate double-blinding, and intention-to-treat analysis were reported in only 50% of the trials. These findings suggest that there is much room for improvement in respiratory RCTs. However, improvement was found in the COPD RCTs, in which there was adequate allocation sequence generation, adequate allocation concealment, and intention-to-treat analysis in 27.0%, 11.6%, and 21.8%, respectively.8 Registered trials, trials cited ≥ 10 times, trials in journals with impact factor ≥ 5, and trials in the general medical journals were more likely to be of adequate methodological quality.. Important aspects of RCT methodology, such as randomization methods, allocation concealment, blinding, and sample-size calculation, are commonly inadequate in RCTs.12 That was the reason we conducted the analysis: to find the related facts on these methodological items. We decided to include trials published in leading journals ...
Background: The quality and quantity of individuals social relationships has been linked not only to mental health but also to both morbidity and mortality.. Objectives: This meta-analytic review was conducted to determine the extent to which social relationships influence risk for mortality, which aspects of social relationships are most highly predictive, and which factors may moderate the risk.. Data extraction: Data were extracted on several participant characteristics, including cause of mortality, initial health status, and pre-existing health conditions, as well as on study characteristics, including length of follow-up and type of assessment of social relationships.. Results: Across 148 studies (308,849 participants), the random effects weighted average effect size was OR = 1.50 (95% CI 1.42 to 1.59), indicating a 50% increased likelihood of survival for participants with stronger social relationships. This finding remained consistent across age, sex, initial health status, cause of ...
BACKGROUND: Insomnia is a widespread complaint in the general population. Wendan decoction has been widely applied in the treatment of primary insomnia. However, to our knowledge, there has been no systematic review or meta-analysis of randomized controlled trails regarding the effectiveness of this treatment. Here, we provide a protocol to evaluate the efficacy and safety of Wendan decoction for primary insomnia. METHODS AND ANALYSIS: Relevant randomized controlled trials in 5 English databases [EMBASE, the Cochrane Central Register of Controlled Trials (Cochrane Library), PubMed, the Allied and Complementary Medicine Databases (AMED), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL)], 4 Chinese databases [Chinese Biomedical Literature Database (CBM), Chinese Medical Current Content (CMCC), China National Knowledge Infrastructure (CNKI), and Wanfang Database] will be comprehensively searched by 2 researchers in October 2017 ...
OBJECTIVES: To survey the frequency of use of indirect comparisons in systematic reviews and evaluate the methods used in their analysis and interpretation. Also to identify alternative statistical approaches for the analysis of indirect comparisons, to assess the properties of different statistical methods used for performing indirect comparisons and to compare direct and indirect estimates of the same effects within reviews. DATA SOURCES: Electronic databases. REVIEW METHODS: The Database of Abstracts of Reviews of Effects (DARE) was searched for systematic reviews involving meta-analysis of randomised controlled trials (RCTs) that reported both direct and indirect comparisons, or indirect comparisons alone. A systematic review of MEDLINE and other databases was carried out to identify published methods for analysing indirect comparisons. Study designs were created using data from the International Stroke Trial. Random samples of patients receiving aspirin, heparin or placebo in 16 centres were used
Publication bias has long been associated with funnel plot asymmetry.10 Among published studies, however, the probability of identifying relevant trials for meta-analysis is also influenced by their results. English language bias-the preferential publication of negative findings in journals published in languages other than English-makes the location and inclusion of such studies less likely.8 As a consequence of citation bias, negative studies are quoted less frequently and are therefore more likely to be missed in the search for relevant trials.7 36 Results of positive trials are sometimes reported more than once, increasing the probability that they will be located for meta-analysis (multiple publication bias).37 These biases are likely to affect smaller studies to a greater degree than large trials.. Another source of asymmetry arises from differences in methodological quality. Smaller studies are, on average, conducted and analysed with less methodological rigour than larger studies. ...

This study is designed to provide clear evidence for health and social policymakers about the influence of alternate service-delivery models and practices on enhancing and sustaining low-income family linkages to available services. A challenge faced by Canadian health and social service providers is to promote health for low-income families in a proactive and cost-effective manner. Families with low incomes experience an array of health and social barriers that compromise their resilience, lead to negative family outcomes, and act as barriers to available services. Family barriers are compounded by service delivery barriers and result in reduced opportunities for effective, primary-level services and in increased use of secondary-level services (e.g., emergency room visits, emergency intervention, police involvement), with the obvious increase in costs. Randomized-controlled trials are rare in community-based intervention research.. This Families First Edmonton randomized-controlled trial (RCT) ...
Febrile neutropenia is a common complication of therapy in children with cancer. Some patients are at low risk of complications, and research has considered reduction in therapy for these patients. A previous systematic review broadly considered whether outpatient treatment and oral antibiotics were safe in this context and concluded that this was likely to be the case. Since that review, there has been further research in this area. Therefore, we aim to provide a more robust answer to these questions and to additionally explore whether the exact timing of discharge, including entirely outpatient treatment, has an impact on outcomes. The search will cover MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, EMBASE, CDSR, CENTRAL, LILACS, HTA and DARE. A full search strategy is provided. Key conference proceedings and reference lists of included papers will be hand searched. Prominent authors/clinicians in the field will be contacted. We will include randomised and quasi-randomised controlled

patients with established coronary artery disease and type-2 diabetes. Brilinta reduced cardiovascular events in patients with no prior heart attack or stroke. The Phase III THEMIS trial met its primary endpoint and demonstrated that Brilinta (ticagrelor), taken in conjunction with aspirin, showed a statistically-significant reduction in a composite of major adverse cardiovascular events (MACE) compared to aspirin alone.. THEMIS was conducted in over 19,000 patients with coronary artery disease (CAD) and type-2 diabetes (T2D) with no prior heart attack (myocardial infarction, MI) or stroke. Preliminary safety results were consistent with the known profile of Brilinta. A full evaluation of the THEMIS data will be presented at a forthcoming medical meeting..

Rivaroxaban and risk of myocardial infarction: insights from a meta-analysis and trial sequential analysis of randomized clinical trials.
In order to avoid selective biases and to minimize random errors, inference about the effects of treatment on serious endpoints needs to be based not on one, or a few, of the available trial results, but on a systematic overview of the totality of the evidence from all the relevant unconfounded randomized trials. But, only where coverage of all, or nearly all, randomized patients in all relevant trials (or a reasonably unbiased sample of such trials) can be assured, is a systematic overview of trials reasonably trustworthy, for then any selective biases are likely to be small in comparison with any moderate effects of treatment. Checks for the existence of such biases can best be conducted if reasonably detailed data are available from each trial. Future trials should take into account the results of any relevant overviews in their design, and should plan to obtain sufficient numbers of events to contribute substantially to such overviews. In many cases, this implies the need for randomized trials that
To summarize data on long-term ipsilateral local recurrence (LR) and breast cancer death rate (BCDR) for patients with ductal carcinoma in situ (DCIS) who received different treatments. Systematic review and study-level meta-analysis of prospective (n = 5) and retrospective (n = 21) studies of patients with pure DCIS and with median or mean follow-up time of ≥10 years. Meta-regression was performed to assess and adjust for effects of potential confounders - the average age of women, period of initial treatment, and of bias - follow-up duration on recurrence- and death-rates in each treatment group. LR and BCDR rates by local treatment used were reported. Outside of randomized trials, remaining studies were likely to have tailored patient treatment according to the clinical situation. Nine thousand four hundred and four DCIS cases in 9391 patients with 10-year follow-up were included. The adjusted meta-regression LR rate for mastectomy was 2.6 % (95 % CI, 0.8-4.5); breast-conserving surgery with

be set to play too loudly. Should all be banned as potentially dangerous? Every practitioner is aware of his/her responsibility to make sure that the device is played at an appropriate level. Basing conclusions on a single, very probably atypical case, is a poor practice-the authors conclusions are not justified.. A good deal of what has been written about AIT is excessively skeptical, negative or derogatory, permeated with the assumption that AIT is ineffective. Our review of all the research on the efficacy of AIT that we have been able to find refutes this negative view.. Probably because AIT lacks a plausible rationale and is counter-intuitive, it has become the target of skepticism and of negatively biased research. Ones opinion about an intervention, like ones opinion about an individual, should be based on evidence rather than prejudice. The present authors were themselves skeptical when first learning about AIT. Their interest was stimulated, despite their initial skepticism, by a ...
Multilevel network meta-regression for population adjustment based on individual and aggregate level data. Abstract: Standard network meta-analysis (NMA) and indirect comparisons combine aggregate data (AgD) from multiple studies on treatments of interest, assuming that any effect modifiers are balanced across populations. We can relax this assumption if individual patient data (IPD) are available from all studies by fitting an IPD meta-regression. However, in many cases IPD are only available from a subset of studies. In the simplest scenario, IPD are available for an AB study but only AgD for an AC study. Methods such as Matching Adjusted Indirect Comparison (MAIC) create a population-adjusted indirect comparison between treatments B and C. However, the resulting comparison is only valid in the AC population without additional assumptions, and the methods cannot be extended to larger treatment networks. Meta-regression-based approaches can be used in larger networks. However, these typically ...

N2 - Background: Aspirin is believed to improve the outcome of IVF, but previous conventional meta-analyses on the subject are conflicting. Therefore, we performed a meta-analysis with individual patient data (IPD MA) of randomized clinical trials (RCTs) on the subject. Methods: A systematic literature search was conducted to identify RCTs assessing the effectiveness of aspirin in IVF. Authors were asked to share their original data. In a one step meta-analytic approach, the treatment effect of aspirin was estimated with odds ratios (ORs) and 95% confidence intervals (CIs) using logistic regression, based on the ...

© 2015 World Stroke Organization. Background: Aspirin is of moderate overall benefit for patients with acute disabling ischemic stroke. It is unclear whether functional outcome could be improved after stroke by targeting aspirin to patients with a high risk of recurrent thrombosis or a low risk of haemorrhage. Aims: We aimed to determine whether patients at higher risk of thrombotic events or poor functional outcome, or lower risk of major haemorrhage had a greater absolute risk reduction of poor functional outcome with aspirin than the average patient. Methods: We used data on individual ischemic stroke patients from three large trials of aspirin vs. placebo in acute ischemic stroke: the first International Stroke Trial (n=18372), the Chinese Acute Stroke Trial (n=20172) and the Multicentre Acute Stroke Trial (n=622). We developed and evaluated clinical prediction models for the following: early thrombotic events (myocardial infarction, ischemic stroke, deep vein thrombosis and pulmonary embolism);

Based on small to moderate effect sizes for the wide range of symptomatic treatments in osteoarthritis (OA), and on the heterogeneity of OA patients, treatment guidelines for OA have stressed the need for research on clinical predictors of response to different treatments. A meta-analysis to quantify the effect modified by the predictors using individual patient data (IPD) is suggested. The initiative to collect and analyze IPD in OA research is commenced by the OA Trial Bank. The study aims are therefore: to evaluate the efficacy of intra-articular glucocorticoids for knee or hip OA in specific subgroups of patients with severe pain and (mild) inflammatory signs, over both short-term and long-term follow-up, using IPD from existing studies; to reach consensus on the rules for cooperation in a consortium; and to develop and explore the methodological issues of meta-analysis with individual OA patient data ...
An Individual Patient Data (IPD) meta-analysis is often considered the gold-standard for synthesising survival data from clinical trials. An IPD meta-analysis can be achieved by either a two-stage or a one-stage approach, depending on whether the trials are analysed separately or simultaneously. A range of one-stage hierarchical Cox models have been previously proposed, but these are known to be computationally intensive and are not currently available in all standard statistical software. We describe an alternative approach using Poisson based Generalised Linear Models (GLMs). We illustrate, through application and simulation, the Poisson approach both classically and in a Bayesian framework, in two-stage and one-stage approaches. We outline the benefits of our one-stage approach through extension to modelling treatment-covariate interactions and non-proportional hazards. Ten trials of hypertension treatment, with all-cause death the outcome of interest, are used to apply and assess the approach. We

According to previous meta-analyses, coffee consumption reduces the risk of type 2 diabetes mellitus. However, the underlying mechanism remains unknown. Whether caffeine, the key ingredient in coffee, has a beneficial effect on the glycemic homeostasis and the anti-diabetic effect is particularly controversial. The aim of this study was to summarize the effect of acute caffeine ingestion on insulin sensitivity in healthy men. A comprehensive literature search for papers published before April 2016 was conducted in EMBASE, PubMed, and Cochrane Library databases. Randomized controlled trials (RCTs) that investigated the effect of caffeine on insulin sensitivity in healthy humans without diabetes were included. A random effects meta-analysis was conducted using Review Manager 5.3. The search yielded 7 RCTs in which caffeine intake was the single variant. Compared with placebo, caffeine intake significantly decreased the insulin sensitivity index, with a standardized mean difference of −2.06 (95%

Ancient Egyptian medical papyri (1550 BC) already emphasised diagnosis by physical examination as the cornerstone of the decision to treat or not to treat an ailment [1]. Today, the clinical assessment of the probability of a disease comes from a series of implicitly and explicitly performed tests. In addition to the implicit diagnostic information from history (risk factors and symptoms) and clinical examination (signs), many additional diagnostic imaging or laboratory tests are available. The accuracy of such tests requires to be appropriately assessed before they can be used in clinical practice.. Studies on primary diagnostic research typically examine the accuracy of a test isolated from history and clinical examination or do not adjust for overlap of information captured by clinical history, physical examination and additional tests. Such studies and conventional meta-analyses of their reported results will therefore not show how useful the test will be in practice [2-4].. In addition to ...
BACKGROUND: There are well over a million homeless people in Western Europe and North America, but reliable estimates of the prevalence of major mental disorders among this population are lacking. We undertook a systematic review of surveys of such disorders in homeless people. METHODS AND FINDINGS: We searched for surveys of the prevalence of psychotic illness, major depression, alcohol and drug dependence, and personality disorder that were based on interviews of samples of unselected homeless people. We searched bibliographic indexes, scanned reference lists, and corresponded with authors. We explored potential sources of any observed heterogeneity in the estimates by meta-regression analysis, including geographical region, sample size, and diagnostic method. Twenty-nine eligible surveys provided estimates obtained from 5,684 homeless individuals from seven countries. Substantial heterogeneity was observed in prevalence estimates for mental disorders among the studies (all Cochrans chi(2)
Harriet L., MacMillan, Professor, Gene Feder, Professor McMaster University and University of Bristol May 18, 2012 Link between evidence and conclusion unclear in USPSTF IPV screening systematic review As two clinician-researchers involved in the intimate partner violence (IPV) screening trial (1) that featured prominently in the recent US Preventive Services Task Force (USPSTF) systematic review on screening women for IPV (2), we were perplexed by the authors conclusion that IPV screening can provide benefits that vary by population. This was the only trial identified as meeting the inclusion criteria to address question 1 of the review: Does screening asymptomatic women in health care settings for current, past, or increased risk for IPV reduce exposure to IPV, physical or mental harms, or mortality? Given that the trial results showed no differences between groups and the overall quality of the study was considered fair, presumably the answer to question 1 would be no - which is what ...

Intermittent claudication is pain in the legs due to muscle ischaemia associated with arterial stenosis or occlusion. Angioplasty is a technique that involves dilatation and recanalisation of a stenosed or occluded artery. The objective of this review was to determine the effects of angioplasty of arteries in the leg when compared with non surgical therapy, or no therapy, for people with mild to moderate intermittent claudication. Sources searched include the Cochrane Peripheral Vascular Diseases Groups Specialized Trials Register (August 2006), the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2006) and reference lists of relevant articles. The review authors also contacted investigators in the field and handsearched relevant conference proceedings (August 2006). Randomised trials of angioplasty for mild or moderate intermittent claudication. The contact author selected suitable trials and this was checked by the other review author. Both review authors assessed trial ...
OBJECTIVE: To systematically review the efficacy and tolerability of fluoxetine, the most widely studied of newer antidepressants, in comparison with all other antidepressants in the acute treatment of depression in patients aged more than 18 years. DATA SOURCES: Studies were identified through electronic searches of the Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register and the Cochrane Central Register of Controlled Trials up to March 2004. The terms FLUOXETIN* OR adofen or docutrix or erocap or fluctin or fluctine or fluoxeren or fontex or ladose or lorien or lovan or mutan or prozac or prozyn or reneuron or sanzur or saurat or zactin were used. MEDLINE (1966-2004) and EMBASE (1974-2004) were searched using fluoxetine and randomized controlled trial or random allocation or double-blind method. No language restrictions were applied. Reference lists of relevant papers and previous systematic reviews were hand-searched for published reports up to March 2004. STUDY
BACKGROUND: Much of the brain swelling in ischaemic stroke is due to cytotoxic oedema, which is related to cell membrane dysfunction. Early treatment with corticosteroids may help reduce the swelling and improve the outcomes after a stroke. OBJECTIVES: The objective of this review was to assess the effect of corticosteroids in acute presumed ischaemic stroke. SEARCH STRATEGY: We searched the Cochrane Stroke Group trials register and contacted investigators in the field. SELECTION CRITERIA: Published randomised trials comparing corticosteroids with placebo or control in people with acute (presumed or definite) ischaemic stroke. Trials were included if treatment began within 48 hours of stroke onset and if clinical outcome was assessed. DATA COLLECTION AND ANALYSIS: Two reviewers independently applied the inclusion criteria, assessed trial quality and extracted the data. MAIN RESULTS: Seven trials involving 453 people were included. Details of trial quality that may relate to bias were not available from
Complementary and alternative medicine (CAM) is increasingly used for treatment of inflammatory bowel disease (IBD). Acupuncture-type treatments are among the most popular options. Several studies have reported that moxibustion is effective in ulcerative colitis (UC). The objective of this review was to assess the clinical evidence for or against moxibustion as a treatment for UC. We searched the literature using 18 databases from their inception to February 10, 2010, without language restrictions. We included randomized clinical trials (RCTs), in which human patients with UC were treated with moxibustion. Studies were included if they were placebo-controlled or controlled against a drug therapy or no treatment group. The methodological quality of all RCTs was assessed using the Cochrane risk of bias. In total, five RCTs were included. All were of low methodological quality. They compared the effects of moxibustion with conventional drug therapy. Three tested moxibustion against sulfasalazine and two

Review authors will work independently to assess risk of bias using criteria described in the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2011) to assess trial quality. This set of criteria is based on evidence of associations between overestimate of effect and high risk of bias of the article such as sequence generation, allocation concealment, blinding, incomplete outcome data and selective reporting. If the raters disagreed, the final rating was made by consensus, with the involvement of another member of the review group. Where inadequate details of randomization and other characteristics of trials were provided, authors of the studies were contacted in order to obtain further information. Nonconcurrence in quality assessment was reported, but if disputes arose as to in which category a trial was to be allocated, again, resolution was made by discussion. The level of risk of bias was noted in both the text of the review and in the Summary of findings tables. ...
Recently, network meta-analysis of survival data with a multidimensional treatment effect was introduced. With these models the hazard ratio is not assumed to be constant over time, thereby reducing the possibility of violating transitivity in indirect comparisons. However, bias is still present if there are systematic differences in treatment effect modifiers across comparisons. In this paper we present multidimensional network meta-analysis models for time-to-event data that are extended with covariates to explain heterogeneity and adjust for confounding bias in the synthesis of evidence networks of randomized controlled trials. The impact of a covariate on the treatment effect can be assumed to be treatment specific or constant for all treatments compared. An illustrative example analysis is presented for a network of randomized controlled trials evaluating different interventions for advanced melanoma. Incorporating a covariate related to the study date resulted in different estimates for the hazard
The authors included non-English trials in the review. The inclusion criteria for the individual trials and their participants were stated, and the author assessed the quality of the primary trials. It was not stated, however, how the trials were selected for inclusion or how study quality was assessed.. The authors listed the primary trials and the data extracted in tabular format, and discussed these data in the review. However, some of the participants details, i.e. age and gender, were not reported consistently.. The authors presented the data in a narrative format but did not report any statistical measurements that were used in the individual trials. This made it impossible to verify the results stated by the authors in this review. Heterogeneity was assessed in the narrative, based on the study characteristics used in the trials.. It was not possible to evaluate whether the authors conclusions were supported by their review due to the lack of primary data reported.. ...

BRILINTA reduced cardiovascular events in these patients with no prior heart attack or stroke. The Phase III THEMIS trial met its primary endpoint which demonstrated that BRILINTA® (ticagrelor) tablets, taken in conjunction with aspirin, showed a statistically-significant reduction in major adverse cardiovascular events (MACE, a composite of cardiovascular death, heart attack and stroke) compared to aspirin alone.. THEMIS was conducted in over 19,000 patients with coronary artery disease (CAD) and type-2 diabetes (T2D) with no prior heart attack or stroke. Preliminary safety results were consistent with the known profile of BRILINTA. A full evaluation of the THEMIS data will be presented at a forthcoming medical meeting.. Elisabeth Björk, Senior Vice President, Head of late Cardiovascular, Renal and Metabolism, R&D BioPharmaceuticals, said: Approaches to help reduce cardiovascular morbidity further in patients with coronary artery disease and type-2 diabetes are urgently needed.

PURPOSE: To compare the effectiveness and adverse event profiles of amylin agonists, DPP-4 inhibitors, incretin mimetics, TZDs, and certain combination products for people with type 2 diabetes and for people with type 1 diabetes for pramlintide only. DATA SOURCES: To identify published studies, we searched MEDLINE, The Cochrane Library, Embase, International Pharmaceutical Abstracts, and reference lists of included studies through July 2010. We also requested dossiers of information from pharmaceutical manufacturers. REVIEW METHODS: Study selection, data abstraction, validity assessment, grading the strength of the evidence (SOE), and data synthesis were all carried out according to standard Drug Effectiveness Review Project methods. RESULTS: Most of the evidence was limited to adult populations. Most of the included studies evaluated intermediate outcomes, such as HbA1c or weight. Very few studies reported health outcomes and few studies were longer than 6 months. For the amylin agonists, ...
