Nomogram for overall survival in ampullary adenocarcinoma using the surveillance, epidemiology, and end results database and external validation

Figure 3 Calibration curves of the prognostic model for 1-, 3-, and 5-year overall survival and cancer-specific survival in the surveillance, epidemiology, and end results training cohort. A-C: Calibration curves of the prognostic model for 1-, 3-, and 5-year overall survival in the surveillance, epidemiology, and end results training cohort; D-F: Calibration curves of the prognostic model for 1-, 3-, and 5-year cancer-specific survival in the surveillance, epidemiology, and end results training cohort. OS: Overall survival; CSS: Cancer-specific survival.
