a Kaplan-Meier survival curves for overall cohort according to BMI (< 25.0 kg/m2 vs. ≥ 25.0 kg/m2). (Note: Group 1, BMI < 25 kg/m2; group 2, ≥ 25 kg/m2). b Kaplan-Meier survival curves for overall cohort according to albumin (< 35.0 g/L vs. ≥ 35.0 g/L). (Note: Group I, serum albumin < 35 g/L; group II, serum albumin ≥ 35 g/L)
