KM survival analysis, risk score assessment by the GRG risk signature and time‐dependent ROC curve in the combined set. (A) KM survival analysis of high‐ and low‐risk samples in the combined set. (B) Relationship between the survival status/risk score rank and survival time (years)/risk score rank. (C) Time‐dependent ROC curve for OS of the combined set. The AUC was assessed at 3 and 5 years. (D) Nine GRGs expression patterns for patients in high‐ and low‐risk groups by the nine‐GRG signature
