Fasting glucose (OR = 1.230, 95%CI 0.593–2.550, P = 0.577), fasting insulin (OR = 2.101, 95%CI 0.731–6.036, P = 0.168), and HbA1c levels (OR = 0.483, 95%CI 0.186–1.253, P = 0.135), as well as genetically predicted type 2 diabetes (OR = 0.926, 95%CI 0.777–1.103, P = 0.388) were also not associated with the risk of AIH after correction for each other. The gene discussed is INS; the disease is autoimmune hepatitis.
