All three multivariable logistic regression models showed positive correlations between ALT/AST and the risk of NAFLD: model 1 (OR = 9.201, 95% CI: 7.536, 11.234), model 2 (OR = 9.732, 95% CI: 7.853, 12.060), and model 3 (OR = 3.648, 95% CI: 2.827, 4.706). Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
