Non-obese individuals with MAFLD had higher BMI, waist circumference, triglyceride, ALT, AST, GGT, uric acid levels, lower systolic blood pressure and high-density lipoprotein cholesterol concentration, younger age, higher prevalence of hyperlipidemia, central obesity, MetS, shorter duration of T2DM, and lower incidence of diabetic retinopathy and diabetic peripheral neuropathy, compared with non-obese participants without MAFLD (p < 0.05), and no statistical difference was observed in hip circumference, waist-to-hip ratio, or total cholesterol between the two groups. Here, GPT is linked to metabolic syndrome.
