The formula for calculating Risk Ratio is straightforward:
RR = [a / (a + b)] / [c / (c + d)]
In this formula, "a" represents the number of individuals in the exposed group who develop the outcome, "b" represents the number of individuals in the exposed group who do not develop the outcome, "c" represents the number of individuals in the non-exposed group who develop the outcome, and "d" represents the number of individuals in the non-exposed group who do not develop the outcome.
