  1. Nutritional status was classified according to the PG-SGA scores: PG-SGA ≥ 9 points (PG-SGA A group); 3 ≤ PG-SGA ≤ 8 points (PG-SGA B group); PG-SGA ≤ 2 points (PG-SGA C group). Continuous variables presented as mean ± s.d. and categorical variables are presented as counts (%). T test/Chi-square test was used between inclusion and exclusion patients
  2. aIn exclusion group, only 130 patients recorded L3 SMI
  3. PA prealbumin, ALB albumin, BMI Body mass index, PhA phase angle, NLR neutrophil-to-lymphocyte ratio, PLR platelet-to-lymphocyte ratio, L3 SMI L3 skeletal muscle index
