The percentages of AST ≥ 30 IU/L (30.8%) and ALT ≥ 30 IU/L (59.4%) in those with NAFLD were significantly higher than in non-drinkers without fatty liver (7.6% for AST ≥ 30 IU/L, p < 0.0001 and 13.4% for ALT ≥ 30 IU/L, p < 0.0001). This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
