Exposed Group:

Non-Exposed Group:



Find the relative risk between two groups with this relative risk calculator. This tool is especially helpful for researchers who are conducting cohort studies for new findings on major diseases. The tool uses the relative risk formula to determine the ratio of exposed and non-exposed groups.

Relative Risk formula:

RR = [a / (a + b)] / [c / (c + d)]
Here,
RR = relative risk
a = number of individuals in the exposed group who got the disease
b = number of individuals in the exposed group who didn't get the disease
c = number of individuals of the control group who got the disease
d = number of members of the control group who didn't get the disease
