R = [ a / (a+b)] / [c/ (c+d))] Where R is the relative risk The relative risk (or risk ratio) is an intuitive way to compare the risks for the two groups. Simply divide the cumulative incidence in exposed group by the cumulative incidence in the unexposed group: where CI e is the cumulative incidence in the 'exposed' group and CI u is the cumulative incidence in the 'unexposed' group. Relative risk is the comparison of one group developing a particular disease to another group.
