The Absolute risk reduction index expresses the statistic reported by Epidemiologists when they conduct a cohort study.
The mathematical difference between the incident rates in the two groups represents the absolute risk reduction. Depending on the underlying event rate, this can change, getting smaller at low event rates and bigger at high event rates.
Simply put, the only way to understand the full context of something presented in a clinical trial is through Absolute Risk Reduction. It is typically significantly less than Relative Risk Reduction (RRR), but it aids in determining how a study conclusion will actually affect people in the real world.
To comprehend the consequences of relative risks and how particular variables or behaviors affect your likelihood of contracting a disease or other health issue, absolute risk figures are required.
