Figure 5. Independent prognostic value of PRGs-based signature. (A) The distribution and median value of the risk scores. (B) The distributions of overall survival status, overall survival, and risk score. (C) The AUC values of time-dependent ROC curves for survival prediction. (D) Kaplan-Meier survival curves showing the overall survival of high- and low-risk LSCC patients divided according to the risk score (log-rank P = 0.007). (E) Prognostic value of the risk scores in the univariate Cox regression analysis (HR = 1.566, 95% CI: 1.284–1.909, P < 0.001). (F) Prognostic value of the risk scores in the multivariate Cox regression analysis (HR = 1.406, 95% CI: 1.126–1.757, P = 0.003). (G) The nomogram for predicting the 1-year, 3-year, and 5-year overall survival. (H) Calibration plot of the nomogram for predicting 1-year, 3-year, and 5-year overall survival.
