Evaluation of the RS model using Kaplan–Meier plot of the training set (divided into high- and low-risk groups based on the median of the risk score) (A), three-year BFS ROC curve (B), and five-year BFS ROC curve (C) predicted using the risk score model (p < 0.05 and AUC > 0.7). K–M plot, Kaplan–Meier plot; TCGA, The Cancer Genome Atlas; AUC, area under the curve; BFS, biochemical recurrence-free survival; ROC, receiver operating characteristic; RS, risk score
