Nomogram based on a novel nutritional immune-inflammatory status score to predict postoperative outcomes in esophageal squamous cell carcinoma

Figure 6 Decision curve analysis of overall survival prediction using the nutritional immune-inflammatory status-nomogram and rationality analysis of the nomogram model. A-F: Decision curve analysis (DCA) of the nomogram, nutritional immune-inflammatory status (NIIS) score, size, age, grade, and pN stage for 1-year overall survival (OS; A); 3-year OS (C); and 5-year OS (E) in the training set. DCA of the nomogram, NIIS score, size, age, Grade, and pN stage for 1-year OS (B); 3-year OS (D); and 5-year OS (F) in the validation set.
