In the training set, shown in Table 2, age (OR = 1.02, 95% CI = 1.01–1.04), WC (OR = 1.09, 95% CI = 1.06–1.12), BMI (overweight vs. nonoverweight, OR = 2.26, 95% CI = 1.49–3.41), serum ALT (abnormal vs. normal, OR = 7.66, 95% CI = 3.81–15.42), and AIP (median vs. low, OR = 1.55, 95% CI = 0.88–2.71; high vs. low, OR = 2.98, 95% CI = 2.04–4.35) were positively associated with NAFLD risk. The gene discussed is GPT; the disease is metabolic dysfunction-associated steatotic liver disease.
