a, C-index (top, blue) measuring model risk discrimination—higher is better—and integrated Brier score (bottom, red) showing overall fit—lower is better—for various time points. b, ROC curve at 10 years for the internal validation and external test cohorts, with the respective areas under the curve (AUROC). c. PR curve at 10 years for the internal validation and external test cohorts, with the respective areas under the curve (AUPR). For all panels, shaded areas represent approximate 95% CIs; solid and dashed lines indicate averages for the internal and external cohorts, respectively; and random chance performance thresholds are shown using dotted lines (the dot-dashed line is used to differentiate the internal random chance performance from the external). The chosen time of 10 years was used to capture all SCDA events in the population.
