An odds ratio is a statistical measure quantifying the strength of association between two binary variables by comparing the odds of an outcome under one condition to the odds under another. It is computed as the ratio of (odds of outcome given exposure A) to (odds of outcome given exposure B), or equivalently as the cross-product ratio from a 2x2 contingency table. The parameters are the two binary variables, the reference category, and the direction of comparison. It persists through statistical reporting, meta-analysis, and evidence-based practice.
