SAL – splenic artery ligation; BMI – body mass index; HBV – hepatitis B virus; HCV – hepatitis C virus; MELD – model of end-stage liver disease; GRWR – graft-to-recipient weight ratio. Continuous variables are expressed as median (IQR). Categorical variables are expressed as number of patients (percentage).
