It was demonstrated that ALT/AST was significantly and positively correlated with the degree of hepatic steatosis in models 1 (β = 70.570, 95% CI: 65.916, 75.224), 2 (β = 67.137, 95% CI: 62.499, 71.774) and 3 (β = 31.551, 95% CI: 26.806, 36.296), while the P for trend was less than 0.001. Here, GPT is linked to fatty liver disease.
