Additional file 1: of Autoantibody detection is not recommended for chronic pancreatitis: a cross-sectional Study of 557 patients

Table S1. Sensitivity and specificity of test method of 22 autoantibodies. Peripheral venous blood samples were obtained from all enrolled patients at admission to detect 22 common autoantibodies (EUROIMMUN Medical Laboratory Diagnostics Stock Company, Lübeck, German), whose sensitivity and specificity were provided in Additional file 1: Table S1. Table S2. Search strategy and result in PubMed (up until May 4th, 2017) In order to compare the frequency of autoantibodies between non-AIP CP patients and healthy controls, a literature search for autoantibodies with frequency > 0.5% was performed through PubMed to identify eligible studies published. These search strategy and result are provided in Additional file 1: Table S2. Table S3. Univariate analysis for smooth muscle antibody, anticardiolipin antibody and anti SS-B antibody in non-AIP CP patients [n(%)]. Univariate analysis result showed that there were no significant differences in all clinical data between patients with positive and negative other three differentially expressed autoantibodies (smooth muscle antibody, anticardiolipin antibody and anti SS-B antibody) (all P > 0.05). Table S4. Related factors for positive smooth muscle antibody in non-AIP CP patients. Univariate logistic regression analysis result showed that there were no related factors for positive smooth muscle antibody in non-AIP CP patients (P > 0.05). Table S5. Related factors for positive anticardiolipin antibody in non-AIP CP patients. Univariate logistic regression analysis result showed that there were no related factors for positive anticardiolipin antibody in non-AIP CP patients (P > 0.05). Table S6. Related factors for positive anti SS-B antibody in non-AIP CP patients. Univariate logistic regression analysis result showed that there were no related factors for positive anti SS-B antibody in non-AIP CP patients (P > 0.05). (DOCX 165 kb
