Evaluation of the nomogram model. A ROC curve of a predictive model that predicts 1-, 3-, and 5-year survival. B-D Calibration curves of prediction models for predicting 1-, 3-, and 5-year survival. The horizontal axis represents the nomogram-predicted survival, and the vertical axis symbolizes the actual survival. The curve in color closest to the 45° gray line gets the best prediction performance
