An odds ratio (OR) is a measure of association between an exposure and an outcome. The OR represents the odds that an outcome will occur given a particular exposure, compared to the odds of the outcome occurring in the absence of that exposure. Odds ratios are most commonly used in case-control studies; however, they can also be used in cross-sectional and cohort study designs as well (with some modifications and/or assumptions).
In statistics, imagine each individual in a population either does or does not have a property ″A,″ and also either does or does not have a property ″B.″ For example, ″A″ might be
