Figure 4 The performance of the nomograms in the validation cohort. A and B: Nomograms of overall survival (OS) and disease-free survival (DFS) based on the training cohort; C: Calibration curves for the nomogram of OS at 3, 5, 7 years in the validation cohort; D: Calibration curves for the nomogram of DFS at 3, 5, 7 years in the validation cohort; E: Receiver operating characteristic (ROC) curves for the nomogram of OS at 3, 5, 7 years in the validation cohort; F: ROC curves for the nomogram of DFS at 3, 5, 7 years in the validation cohort; G and H: Decision curve analyses (DCA) for the nomograms of OS (G) and DFS (H) at 3, 5, 7 years in the validation cohort. OS: Overall survival; DFS: Disease-free survival; AUC: Area under the curve; post-CEA: Postoperative carcinoembryonic antigen; AJCC: American Joint Committee on Cancer; CI: Confidence interval.
