APOA1 and autoimmune hepatitis: Consistent with the findings of univariate analysis, genetically predicted levels of TG (OR = 0.884, 95%CI 0.646–1.210, P = 0.442), HDL(OR = 0.919, 95%CI 0.685–1.233, P = 0.575), LDL (OR = 0.897, 95%CI 0.655–1.229, P = 0.500), and ApoA1 (OR = 0.870, 95%CI 0.656–1.154, P = 0.334) were not significantly causally associated with the risk of AIH after adjusting for genetically predicted HDL/LDL, TG/LDL, TG/HDL, and TG/LDL, respectively.
