Classification ability of serological epithelial component proteins for Complicated Crohn's disease. Total DSG1, DSK, and FABP5 levels were able to classify: A, CD against RA, UC, and control groups, B, CCD against ICD, RA, UC, and controls, and C, CCD against ICD. The putative Serological Epithelial Component (SEC) score, developed using discriminant function coefficients of the biomarker candidates, improved classification of CD and CCD in all cases: D, CD against RA, UC, and control groups, E, CCD against ICD, RA, UC, and controls, and F, CCD against ICD.
