Anthropometric traits such as weight, BMI, waist circumference, hip circumference and waist to hip ratio (p < 0.001) and serum traits such as ALT, fasting glucose, hemoglobin, TC, LDL, and TG (p < 0.050) were significantly lower in lean non-NAFLD individuals than lean NAFLD individuals. This evidence concerns the gene GPT and metabolic dysfunction-associated steatotic liver disease.
