Probability of an adverse outcome (eg, death) in a randomized trial plotted against the level of an adverse risk factor (eg, prostate-sdoubling time at recurrence). Black line: Control group. Light grey: Treatment group where treatment has a constant relative risk reduction, a 50% reduction in risk. Dashed line: Treatment group where treatment is associated with a constant absolute risk reduction of 5%. Note that if relative risk reduction is constant different levels of the prognostic factor, absolute risk reduction varies and vice versa.
