Clinical characteristics and outcome of autoimmune pancreatitis based on serum immunoglobulin G4 level: A single-center, retrospective cohort study

Figure 3 Univariate and multivariate Cox regression analysis for relapse of autoimmune pancreatitis. Univariate Cox regression analysis indicated that age (> 55 years), immunoglobulin (Ig)A (> 400 mg/dL), IgG4 (> 402 mg/dL), presence of thickened bile duct were risk factors of relapse of autoimmune pancreatitis. Multivariate Cox regression analysis identified three risk factors of relapse, including age (> 55 years), IgA (> 400 mg/dL) and IgG4 (> 402 mg/dL). ¹Others: Hepatic protectors, antibiotics and proton pump inhibitors. PLT: Hemoglobin; Ig: Immunoglobulin; ESR: Erythrocyte sedimentation rate; C3: Complement C3.
