a Comparison of ROC curves for the Deep Learning Survival Cox model and the Cox proportional hazards model on the training-validation set. b The Kaplan–Meier curves for developing critical illness among patients in different risk groups in the training set. Shaded areas indicate 95% confidence interval. c ROC curves for the three external validation cohorts using the entire datasets. d ROC curves for the three independent external validation cohorts, excluding patients that were missing more than three values.
