Osteoarthritis - Evidence
OR (odds ratio)
The odds ratio (OR) is the ratio between the odds of the treated group and the odds of the control group.
- OR is a common measure of the size of an effect and may be reported in case-control studies, cohort studies, or clinical trials. It can also be used in retrospective studies and cross-sectional studies, where the goal is to look at associations rather than differences.
