Receiver operating characteristic (ROC) curves. ROC curve analysis of discrimination between cases with active celiac disease (CD) and without CD (A and B) or between cases with active CD and normalized CD (C). ROC curves in (A) correspond to CXCL11 protein (solid line), TNFSF13B messenger RNA (mRNA) (dashed line), and a logistic regression model of CXCL11 protein and TNFSF13B mRNA (dotted line). ROC curves in (B) correspond to tissue transglutaminase autoantibodies (anti-TG2) (solid line) and a logistic regression model of anti-TG2, CXCL11 protein, and TNFSF13B mRNA (dashed line). ROC curves in (C) correspond to anti-TG2 (solid line), TNFRSF9 mRNA (dashed line), and a logistic regression model of anti-TG2 and TNFRSF9 mRNA (dotted line).
