In the observation group of the mild fibrosis subgroup, ALT levels were higher than in the control group, but the difference was not statistically significant (P > 0.05); in the observation group of moderate-severe fibrosis subgroups, ALT levels were also higher than those in the control group, and the difference was statistically significant (P < 0.05) (details can be found in Table 6). The gene discussed is GPT; the disease is fibrosis.
