Relative risk (RR) is used to compare the risk of a certain event or outcome occurring between two groups, typically an exposed group and an unexposed group, allowing researchers to understand the strength of the association between a specific exposure (such as a risk factor or treatment) and the outcome of interest (such as a disease). For example, a relative risk greater than 1 indicates that the exposure is associated with a higher risk of the outcome, while a relative risk less than 1 suggests a protective effect of the exposure against the outcome.
