  1. BMI body mass index, ACCI age-adjusted Charlson comorbidity index, HB hemoglobin
  2. Values are mean ± standard deviation or number (percentage) as appropriate. P < 0.05, statistical significance. In this study, anemia was defined as hemoglobin level < 120 g/L for males and < 110 g/L for females; Hypoproteinemia refers to serum albumin less than 35 g/L
