Serum AST (33.0 ± 17.1 U/L vs. 23.8 ± 8.8 U/L, p < 0.001), serum ALT (39.2 ± 30.9 U/L vs. 20.0 ± 12.8 U/L, p < 0.001), cholinesterase (350.1 ± 89.2 U/L vs. 319.4 ± 78.6 U/L, p = 0.001), and gamma-glutamyl transferase (50.8 ± 44.1 U/L vs. 32.3 ± 41.0 U/L, p < 0.001) were all significantly higher in the non-obese NAFLD group. This evidence concerns the gene BCHE and metabolic dysfunction-associated steatotic liver disease.
