Prospective model ROC and PR curves. Prospective model ROC and PR curves using five-fold cross validation. Binary prospective model results predicting CVRV or not during admission are shown in a–l. Panels a–f and g-l are AUCs and PR curves, respectively, using 4 h, 1 day, 3 days, 5 days, 7 days, and 10 days of ICU data since ICU admission. Trinary prospective model results predicting CVRV in ≤ 3 days, CVRV in >3 days, or no CVRV during admission, are shown in panels m–o, which show AUC curves using 1 day, 5 days, and 10 days of ICU data since ICU admission.
