  1. Post-LT HGG was assessed at postoperative 1 month. Post-LT HGG and rejection were used as time-varying variables. HGG was defined as a measured IgG level of < 700 mg/dL7.
  2. BMI, body mass index; CI, confidence interval; HCC, hepatocellular carcinoma; HGG, hypogammaglobulinemia; HR, hazard ratio; LT, liver transplantation; MELD, model for end-stage liver disease; RBC, red blood cell.
