Odds ratios and interpretations

Research papers may include an odds ratio. This ratio measures the association between an intervention or exposure, and an outcome.

What are the odds?

Odds are different to probabilities. In classical statistics, probabilities are the long-run frequency of an event. In Bayesian statistics, probabilities represent a state of knowledge or reflect personal belief.
