Kaplan–Meier curves for overall survival time of cancer patients in different nutrition status diagnosed by PG-SGA. A Kaplan–Meier survival analysis stratified by PG-SGA. Well nourished (0–1) = Stage A; Mild or Moderate malnutrition (2–8) = Stage B; Severe malnutrition (> = 9) = Stage C. B Kaplan–Meier survival analysis stratified by PG-SGA. Well nourished (0–1); Mild malnutrition (2–3); Moderate malnutrition (4–8); Severe malnutrition (> = 9). Overall survival between different nutrition status groups were analyzed and compared by Kaplan–Meier analysis and log Rank test. PG-SGA Patient-Generated Subject Global Assessment
