Proportion of subjects with serum retinol and α-tocopherol levels according to quartile with predicted NAFLD prevalence (HSI) by quartile. The study population was divided into quartile groups according to NAFLD (HSI) and vitamin (serum retinol and α-tocopherol) levels, respectively. Serum retinol and α-tocopherol had strong positive associations with the NAFLD (HSI) prediction model (ps < 0.0001 for the trends). NAFLD, non-alcoholic fatty liver disease; HSI, hepatic steatosis index; Q, quartile.
