  1. The incidence rates are not the assumed CHD or stroke rates for the hypothetical population in the probabilistic sensitivity analysis. The ratio of the two incidence rates is used in the probabilistic sensitivity analysis to partition the reduction of an ASCVD event into a CHD event reduction and a stroke event reduction
