Video describing how relative risk is calculated from a cohort study. RR is just a ratio of incidence of the outcome in the exposed divided by the incidence

Relative Risk Reduction (RRR) Relative risk reduction is how much risk is reduced in an experimental group compared to a control group. The formula is: (CER – EER)/CER Where: CER = control group event rate, If the relative risk = 1, then there is no difference in risk between the two groups. If the relative risk is less than 1, then there is less risk in the exposed group relative to the unexposed group. If the relative risk is greater than 1 (as in the example), then there is greater risk in the exposed group relative to the unexposed group. • The relative risk reduction is the difference in event rates between two groups, expressed as a proportion of the event rate in the untreated group. For example, if 20% of patients die with treatment A, and 15% die with treatment B, the relative risk reduction is 25%. If the treatment works equally well Relative Risk Formula.
