Construction of a prognostic model. (A) Kaplan–Meier survival curves indicated that the probability of premature death was higher in high-risk subgroup patients than in low-risk subgroup patients. (B) Time-dependent Receiver Operating Characteristic (ROC) curves were plotted to validate the prognostic model, with good discrimination in 2, 3, and 5 years. (C) Nomogram based on multivariate Cox regressions to predict the survival probability of OS patients. (D) Calibration curves of the nomogram, demonstrating a high prediction accuracy.
