Fig. 6: Clinical prognostic nomogram for survival prediction.

A A clinical prognostic nomogram was developed to predict 1-, 3-, and 5-year survival. Calibration curves showing nomogram predictions for 1-year (B), 3-year (C), and 5-year (D) survival. E Time-dependent ROC curve analyses for predicting OS at 5 years by risk score age, sex, stage, T stage (tumor size), M stage (distant metastasis), and N stage (lymph node metastasis).
