  • Intra-observer variances were 0.001 +/- 0.001 mm2 for cup area (mean +/- SD), 0.002 +/- 0.002 mm2 for disc area and 0.002 +/- 0.003 mm2 for rim area. (nih.gov)
  • These values for intra-observer variance were comparable with the results obtained using manual planimetric techniques. (nih.gov)
  • Intra-observer variance for disc area was significantly larger for the less trained of the two experienced observers. (nih.gov)

  • Inter-observer variances were 0.004 +/- 0.009 mm2 for cup area, 0.008 +/- 0.013 mm2 for disc area and 0.009 +/- 0.014 mm2 for rim area. (nih.gov)
  • These inter-observer variances were significantly larger than those previously reported for manual planimetry. (nih.gov)
  • Morphological variability or inter-observer bias? (researchgate.net)
  • There was a considerable variation in the reading of the slides between different persons. (erowid.org)
  • Although genetic variation is a major driving force behind evolution, certain variants also underlie many congenital diseases. (mlo-online.com)
  • Copy number variants (CNVs) are a major source of such genetic variation, and are defined as chromosomal segments at least one thousand bases in length that vary in copy number between individuals. (mlo-online.com)
  • Although information on both types of genetic variation is complementary in many of these investigations, each has traditionally been analyzed using separate approaches. (mlo-online.com)
  • And the other reason is for less variation between seasonal and monthly statistics from year to year. (mountwashington.org)
  • The wide geographic variation in the ecology and behavior of vectors, pathogens, reservoirs, and persons is likely to cause corresponding variation in cost-effectiveness of control measures ( 16 ). (cdc.gov)
  • While much research has examined variation in mobbing responses to different predators, few studies have investigated how anti-predator behavior is affected by changes in a predator's own state or behavior. (springer.com)
  • Previous research has reported levels of agreement between parents' and teachers' report of children's behavior, but relatively little attention has been paid to the agreement between teachers or between teachers and observers. (umass.edu)
  • Objectives: The investigation of morphological variation in animals is widely used in taxonomy, ecology, and evolution. (researchgate.net)
  • The findings suggest that a graduated measure is useful for assessing the degree of uncertainty of the observers and subtle effects of different factors upon the judgment of patient's pain. (researchgate.net)
  • To make sense of these findings, it is important to remember that most observers think that the Census of Fatal Occupational Injuries (CFOI) provides a good count of traumatic occupational deaths, while there are many concerns about underreporting in the Survey of Occupational Injuries and Illnesses (SOII). (cdc.gov)
  • Inter-teacher agreement, and some types of teacher-observer agreement, showed significant variation across informant pairs. (umass.edu)
  • Procedure -TDI was performed by the same trained observer (VC) on all cats. (avma.org)
  • A trained observer must also supervise each step of every PPE donning/doffing procedure to ensure established PPE protocols are completed correctly. (cdc.gov)
  • We studied monocular OKN in ten observers with early-onset (up to 24 months of age), seven observers with late-onset (after 24 months of age) unilateral strabismus, and 12 normally sighted control observers. (nih.gov)
  • Masked measurements were made 3 times by 2 observers, from stereophotographs of the optic nerve head of 56 eyes from 30 glaucoma suspects. (nih.gov)
  • Several reports on monocular optokinetic nystagmus (OKN) in observers with strabismus have found that asymmetry of OKN tends to occur in both eyes of observers with an early onset of strabismus but only in the deviating eye of those with a later onset of strabismus. (nih.gov)
  • In general, teacher-observer agreement has been found to be superior to parent-teacher agreement, but inferior to inter-teacher agreement. (umass.edu)
  • The prevalence of CNVs throughout the general population suggests that they represent a significant proportion of total genomic variation, and it has been estimated that CNVs may affect as much as 4% to 5% of the human genome. (mlo-online.com)
  • The absolute differences between the two observers ranged from -0.35 to +0.20 mm2 (-0.08 +/- 0.11 mm2) for cup area, from -0.38 to +0.15 mm2 (-0.08 +/- 0.11 mm2) for disc area and from -0.29 to +0.34 mm2 (-0.06 +/- 0.12 mm2) for rim area. (nih.gov)
  • In the deviating eye, observers with early-onset strabismus showed large OKN asymmetries in favour of nasalward motion while observers with late-onset strabismus showed smaller OKN asymmetries in that eye. (nih.gov)
