Considering only patients with liver biopsy, the 15 in the PNALT group showed a lower histological activity index (HAI) (3.47±2.47 vs. 6.04±3.5, p = 0.0001), lower fibrosis (1.27±0.59 vs. 2.39±1.44, p = 0.0001) and lower steatosis scores (0.33±0.62 vs. 1.21±1.26, p = 0.0001) than the 171 patients in the abnormal ALT group (Table 1). The gene discussed is GPT; the disease is steatosis.
