Prognostic value of the model. A, B Kaplan–Meier survival analysis and time-dependent ROC analysis to predict the overall survival of patients in the ICGC cohort. These predictions were based on the risk score. C, D Univariate and multivariate regression analyses of the ICGC cohort to examine the association between risk score and clinicopathological characteristics in terms of overall survival. Green represents univariate analysis; red represents multivariate analysis. E, F Forrest plots of TCGA and ICGC cohorts based on univariate and multivariate Cox analyses
