Relative Risk
The ratio of the probability of an event in the exposed group to the probability in the unexposed group.
Definition
Relative risk (RR), also called risk ratio, is used to compare event rates between treatment and control groups. In health economic models, relative risks from clinical trials are applied to baseline event rates to derive treatment-specific transition probabilities. An RR < 1 indicates the treatment reduces the risk of the event.
