Figure 5. DCA for the prognostic nomogram. (A-F) DCA curves for 1-, 3-, and 5-year OS in the training and validation cohorts: 1-year OS in the training cohort (A) and validation cohort (B); 3-year OS in the training cohort (C) and validation cohort (D); 5-year OS in the training cohort (E) and validation cohort (F). The nomogram was compared with the TNM staging system, “Treat All”, and “Treat None” strategies. The Y-axis represents net benefit. The nomogram provided greater net benefit than the TNM staging system for 3- and 5-year OS, while the benefit was comparable or slightly better for 1-year OS. DCA: Decision curve analysis; OS: overall survival; TNM: tumor-node-metastasis.
