How do you interpret a risk difference of 1
WebDec 20, 2024 · To calculate the attributable risk, one simply subtracts the risk for the non-exposed group from the risk for the exposed group. Thus, attributable risk is sometimes called the Risk Difference, or Excess Risk. The excess risk is “attributed” to the exposure. The risk difference (RD), excess risk, or attributable risk is the difference between the risk of an outcome in the exposed group and the unexposed group. It is computed as , where is the incidence in the exposed group, and is the incidence in the unexposed group. If the risk of an outcome is increased by the exposure, the term absolute risk increase (ARI) is used, and computed as . Equi…

Tips For Interpreting Risk Difference Tip #1: If you have cumulative incidence expressed as percentage, convert % to convenient fractions so that you can express it as the excess risk in a group of people who have the risk factor. Example: CI with appendectomy = 5.3% = 53/1000 CI without appendectomy = 1.3% … See more Instead of comparing two measures of disease frequency by calculating their ratio, one can compare them in terms of their absolute difference.
