Figure 3. Nomogram analyses of the selected prognostic factors. (A) A nomogram was built using four independent prognostic factors. (B) Time-dependent ROC was employed to weigh up the performance of nomogram model. (C) Calibration curves for nomogram model related to 1-, 3-, and 5-year OS. (D–F) DCA for nomogram model related to 1-, 3-, and 5-year OS.
