Calibration curves of prediction models for predicting the 1-, 3-, and 5-year survival. The clinical parameters model for predicting 1-, 3-, and 5-year a OS and c PFS. The combined model of NPS and clinical parameters for predicting 1-, 3-, and 5-year b OS and d PFS. 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 dotted line gets the best prediction performance. OS overall survival, PFS progression-free survival
