(b) Kaplan-Meier curves for the OS of patients in the high-risk group and low-risk group in the TCGA cohort. (c) AUC of time-dependent ROC curves verified the prognostic performance of the risk score in the TCGA cohort. (d) Alluvial diagram showing the changes of FRG clusters, FRG score, risk score, and survival state.
