Risk score analysis of the prognostic signature based on training and test subsets. A Kaplan–Meier survival curve analysis of BCRs between the high- and low-risk groups in the training subset. B 1-year, 3-year, and 5-year ROC curves of PCa patients in the training subset. C Risk score and survival status of each PCa patient in the training subset. D Heatmap of prognostic MTGs expression based on the risk score and clinical characteristics in the training subset. E Kaplan–Meier survival curve analysis of BCR between the high- and low-risk groups in the test subset. F 1-year, 3-year, and 5-year ROC curves of PCa patients in the test subset. G Risk score and survival status of each PCa patient in the test subset. H Heatmap of prognostic MTGs expression based on the risk score and clinical characteristics of the test subset
