Estimation of the model. ROC curve in training cohort (A). ROC curve in testing cohort (B). Time-dependent ROC curve analysis of survival prediction by the prognostic model. Calibration curves in training cohort (C). Calibration curves in testing cohort (D). The Y-axis represents actual survival, as measured by K–M analysis, and the X-axis represents the model-predicted survival. Survival analysis of patients with GNB in the training (E) and testing (F) sets. The K–M survival curves show the overall survival based on the high and low-risk patients divided by the optimal cut‐off point.
