WebbIf the study outcome is suﬃciently rare among exposed and unexposed study subjects, the odds ratio for the exposure–outcome association will closely approximate the risk ratio. But if the outcome is common and the risk ratio is not close to 1, the odds ratio will be further from 1 compared with the risk ratio.
