Abstract
Relative Risk, also described as risk rate or risk index, is a measure that quantifies the effect of an exposure in relative terms. In epidemiology and statistics, the relationship between two incidence rates corresponds to a risk relationship. The Relative Risk does not provide any information about the absolute risk of an event or outcome of interest. The value of the Relative Risk can take any value between zero and infinity.
