Specificity13
- The properties of a diagnostic or screening test are often described using sensitivity and specificity or predictive values, as described in previous Notes. (bmj.com)
- The positive likelihood ratio is the proportion with obstructive airway disease who smoked more than 40 pack years (sensitivity) divided by the proportion without disease who smoked more than 40 pack years (1-specificity), 28.4/1.4 = 20.3, as before. (bmj.com)
- The negative likelihood ratio is the proportion with disease who smoked less than 40 pack years (1-sensitivity) divided by the proportion without disease who smoked less than 40 pack years (specificity), 71.6/98.6 = 0.73. (bmj.com)
- However, unlike sensitivity and specificity, computation of likelihood ratios does not require dichotomisation of test results. (bmj.com)
- Sensitivity, specificity, predictive values, likelihood ratios, and posttest probabilities were estimated according to standard definitions ( 5 ). (cdc.gov)
- Performance characteristics (sensitivity, specificity, predictive values, and likelihood ratios) of tests were measured by comparing test results with findings on colonoscopy. (nih.gov)

Ratio14

- More formally, it is the ratio of the probability of the specific test result in people who do have the disease to the probability in people who do not. (bmj.com)
- A likelihood ratio greater than 1 indicates that the test result is associated with the presence of the disease, whereas a likelihood ratio less than 1 indicates that the test result is associated with the absence of disease. (bmj.com)
