In epidemiology, risk ratio (RR) or relative risk is the ratio of the probability of an outcome in an exposed group to the probability of an outcome in an unexposed group. It is computed as /, where is the incidence in the exposed group, and is the incidence in the unexposed group. Together with risk difference and odds ratio, risk ratio measures the association between the exposure and the.
