Assessment of the risk model in the validation cohort. A Risk scores were calculated for each patient using the model above, with a cutoff value of 0.4027 for low- and high-risk groups. The distribution and survival status of these patients were plotted. B Kaplan–Meier curves. C Time-dependent ROC curves of 1, 2, and 3 years. D Calibration curves. E DCA curve of 1 year. F DCA curve of 2 years. G DCA curve of 3 years
