The results of univariate analysis showed IgA, C3, and ALT might be the risk factors for steatosis (>33%, Supplementary Table S5), ANA and C3 might be the risk factors for ballooning, and ANA, IgA, and C3 may be the risk factors for NAS (≥5, Supplementary Table S6). The gene discussed is GPT; the disease is steatosis.
