AUC = area under the curve; AFLD = alcoholic fatty liver disease; NAFLD = non-alcoholic fatty liver disease; YKL-40 = human cartilage glycoprotein-39; MMP-2 = metalloproteinase 2; TIMP-1 = tissue inhibitor metalloproteinase 1; AAR = aspartate to alanine aminotrasferase ratio; APRI = AST to platelet ratio index; GUCI = Goteborg University Cirrhosis Index.
