However, ROC analysis apoA1 (AUC: 0.700; 95% CI 0.627–0.773), apoE (AUC: 0.788; 95% CI 0.722–0.854) in AIC, apoA1 (AUC: 0.567; 95% CI 0.488–0.645), apoE (AUC: 0.587; 95% CI 0.506–0.667) in AIH showed apoA1 and apoE were not ideal diagnostic indicators. The gene discussed is APOE; the disease is autoimmune hepatitis.
