Independent prognostic factors and K-M survival curves of the OS stratified by different clinicopathologic features between the high- and low-risk groups in the TCGA set. A ROC analysis of the m7G prognostic model in the training, test, and TCGA sets, respectively. B-C Forest plot of the univariate Cox regression analysis (B), and the multivariate Cox regression analysis (C) of the risk score and clinicopathologic features with the OS in the TCGA set. D K-M survival analysis of the OS stratified by age (< 65 or ≥ 65), M stage (M0 or M1), T stage (T1-2 or T3-4), and tumor stage (I-II or III-IV)
