  1. Values are expressed as median (IQR) for non-normally distributed continuous variables and n (%) for categorical variables. Continuous variables were compared using Mann-Whitney U test due to non-normal distribution. Categorical variables were compared using chi-square test. Bold P values indicate statistical significance (P<0.05). FIB-4 index was calculated as: (Age × AST)/(Platelet count × √ALT). FIB-4 categories were stratified according to a recent meta-analysis and Chinese guidelines for metabolic dysfunction-associated fatty liver disease: minimal fibrosis (FIB-4 ≤1.30), significant fibrosis (1.30< FIB-4 <2.67), and advanced fibrosis (FIB-4 ≥2.67). Abbreviations: mRS, modified Rankin Scale; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; FBG, fasting blood glucose; ALT, alanine aminotransferase; AST, aspartate aminotransferase; FIB-4, Fibrosis-4 index.
