Receiver Operating Characteristic Curve for 1-year mortality among admitted patients in the emergency department. a The area under the ROC curve (AUROC) is 0.762 (0.742–0.782) for the A-qCPR risk score in the training cohort with cross-validation. b The area under the ROC curve from the out-of-time validation sample is 0.694 (0.688-0.700) for the A-qCPR risk score, 0.590 (0.587–0.594) for PPS, 0.539 (0.536–0.542) for qSOFA, and 0.565 (0.562–0.568) for SQ. [PPS: Eastern Cooperative Oncology Group Performance Status Score; qSOFA: Quick Sequential Organ Failure Assessment; SQ: Surprise Question]. c ROC curves for 1-year mortality based on the training cohort validated predicted probabilities for the A-qCPR screening tool, the area under the ROC curve is 0.694 (0.688–0.701) in the out-of-time validation sample, and it is 0.691 (0.682-0.700) and 0.698 (0.689–0.707) in the validation cohort a and b, respectively
