BTG3 and autoimmune hepatitis: Based on the result of univariate cox regression, multivariate cox regression analysis showed that ANA negative (HR: 0.21, 95%CI: 0.13–0.35, P < 0.001), MPV (HR: 1.25,95% CI: 1.11–1.4, P < 0.001), serum K (HR: 0.93, 95%CI: 0.87–0.99, P = 0.019) and INR (HR: 2.22, 95% CI: 1.63–3.03, P < 0.001) can be used as independent predictors of poor prognosis in AIH patients (Fig. 3).
