Development of the prognostic risk signature based on DNA methylation. Kaplan–Meier curve analysis presenting difference of overall survival between the high-risk and low-risk groups in the training group (A), testing group (B), and combination cohort (C). ROC curve analysis of the risk scores for overall survival predictive significance in the training group (D), testing group (E), and combination cohort (F). The AUC was calculated for ROC curves, and sensitivity and specificity were calculated to assess score performance. Univariate Cox regression analyses of overall survival in the training group (G), testing group (H), and combination cohort (I). Multivariate Cox regression analyses of overall survival in the training group (J), testing group (K), and combination cohort (L).
