^aVariables were logarithmized (base 2) to achieve normal distribution; Variables FFP (fresh frozen plasma), colloids, and albumins were not included into analysis because of high correlation with RBC – to avoid multicollinearity; Nagelkerke R² = 0.231. ALC: Alcohol related liver disease; BMI: Body mass index; Hb: Haemoglobin; HBV: Hepatitis B virus; INR: International normalised ratio; MELD: Model of End-stage Liver Disease; Na: Sodium; RBCs: Red blood cells.
