Diagnostic performance of serum IFN-α and IL-33 concentrations for type 1 autoimmune pancreatitis and IgG4-related disease. Receiver operating characteristic curve analysis was performed to assess the utility of serum IFN-α, IL-33, IgG1, and IgG4 levels as biomarkers of type 1 autoimmune pancreatitis and IgG4-related disease. The area under the curve (AUC) was calculated for each biomarker.
