Distributions of risks for model A and model B displayed with cumulative distribution function curves. The high risk category is defined as risk exceeding 20%. Approximately 10% of the population is classified as high risk with model B but only 1% with model A. Approximately 26% of cases, i.e. those that had an event in the absence of intervention, are classified as high risk with model B but only 2% with model A. Of control subjects, that is those who did not have an event, 8% and 1%, respectively, are classified as high risk according to models B and A.
