In binary logistic regression analysis, only log leptin [OR 1.29 95% (C.I) (1.11–1.51), P = 0.001] in male subjects as well as HOMA%B [OR 0.94 95% (C.I) (0.89–0.98), P = 0.012], HOMA-IR [OR 3.30 95% (C.I) (0.99–10.95), P = 0.049] and log leptin [OR 1.10 95% (C.I) (1.01–1.20), P = 0.026] in female subjects were found to be independent determinants of NAFLD after adjusting the BMI and TG. The gene discussed is LEP; the disease is metabolic dysfunction-associated steatotic liver disease.
