Predicted vs observed probability of incident diagnosis of heart failure in a contemporary, diverse electronic health record-based cohort stratified by A) White Men, B) White Women, C) Black Men, D) Black Women. Predicted probability estimated using modified Pooled Cohort Equation to Prevent Heart Failure (PCP-HF) model. In each race-sex group, patients were categorized into deciles based on predicted probability of incident heart failure. Observed probability was defined by established criteria using Internal Classification of Disease codes.
