Note that the odds are not the inverse of the event rate. Odds ratio describes the odds of an experimental patient having an event relative to a control patient. Overview is a systematic review and summary of the medical literature. Postmarketing surveillance study is a study that tracks the use and adverse effects of a medication once it has been approved for use in the general population. The more a curve arches into the upper-left corner, the greater the area under the curve, and the better the test.
Sensitivity is the proportion of people with disease who have a positive test result.
Sensitivity analysis is used to determine whether plausible variations in input parameters alter the results and conclusions of a study. Specificity is the proportion of people free of a disease who have a negative test result. Systematic review is an unbiased review of the literature that uses an explicit strategy to find the relevant studies, predefined criteria for assessing studies, and structured presentation of the results. Treatment effect is the difference in outcome that can be attributed specifically to the experimental treatment compared with the control treatment. Z statistic is calculated by dividing the difference of sample proportions by the standard error of the difference of sample proportions.
