Nomogram of the prognostic model. a Nomogram of the prognostic model. b Calibration curve evaluating the calibration of nomogram according to the agreement between the predicted OS and observed outcome. i The predicted 3-year OS and observed outcome. ii The predicted 5-year OS and observed outcome. The y-axis represents actual survival estimated by the nomogram, and the x-axis represents the predicted probability of survival. The reference line represents a perfect prediction by an ideal model.c i The DCA curves of the nomograms compared for 3-year OS. ii The DCA curves of the nomograms compared for 5-year OS. The all negative line indicates that no patients survive. The all positive line indicates that all patients survive. The NLR + PLR + MLR line shows the clinical net benefits of all factors, including age, stage, grade, histopathological subtype, lymphovascular space invasion, NLR, PLR, and MLR, while the baseline shows the clinical net benefits of all factors excluding NLR, PLR, and MLR.d The AUC of time-dependent ROC of the nomogram
