Risk score performance in time to event analysis and cross-sectional analysis. (A) The Kaplan–Meier plot of patients stratified into tertiles by the risk score (N = 475). (B) The receiver-operating-characteristic (ROC) curve of the risk score for classifying patients with or without HCC at 1 year after recruitment. The area under the ROC (AUC) is 0.697. (C) The ROC curve for classifying patients at 2 years after recruitment (AUC = 0.751). (D) The ROC curve for classifying patients at 3 years after recruitment (AUC = 0.766).
