External validation time-dependent ROC curves for long-term outcomes. Time-dependent ROC curves in the external validation cohort at 12 and 24 months. (a) All-cause mortality at 12 months. (b) All-cause mortality at 24 months. (c) Cause-specific mortality at 12 months. (d) Cause-specific mortality at 24 months. Final models are highlighted; AUCs are shown in the legend.

ROC, receiver operating characteristic; RSF, random survival forest; AUC, area under the curve; GBM, gradient boosting machine; LASSO, least absolute shrinkage and selection operator.
