Comparison of TMB and stemness analysis based on DRGPS risk score. a, b Waterfall maps of the somatic mutations in the high-risk group and the low-risk group; c difference in TMB between high and low risk groups; d difference in survival probability between high and low TMB groups; e Kaplan–Meier analysis of the combination of TMB group and DRGPS risk score. f, g Correlation analysis of risk scores with the stemness index RNAss and EREG.EXPss; h stemness analysis of risk score in pan-cancer. TMB, tumor mutation burden; DRGPS, DRG prognostic signature. The P values were shown as *P < 0.05; **P < 0.01; and ***P < 0.001
