calibration plot and decision curve analysis for PG-SGA SF. A Calibration curves of the TNM stage combined with PG-SGA SF model. B Decision curve analysis on the TNM stage (black line), and TNM stage combined with PG-SGA SF (red line). Gray line denotes the assumption that all patients have outcome event (death) during follow-up. Thick black line represents the assumption that no patients have outcome event (death) during follow-up
