In the aspect of liver histology, the results indicated that normal ALT was related to steatosis grade (1 vs 2–3; OR = 4.30, 95% CI: 2.35–7.87; P = 0.10) and lobular inflammation (0–1 vs 2–3; OR = 3.35, 95% CI: 1.52–7.34; P = 0.36) in NAFLD patients (Table 4). The gene discussed is GPT; the disease is metabolic dysfunction-associated steatotic liver disease.
