Table 2. Sensitivity, specificity, and ROC values for ELISA results with r-PROE (Proproteinase E) and r-IGLL1 (Immunoglobulin lambda-like polypeptide-1) as antigens.
ROC analyses were performed to compare the index values of r-PROE and r-IGLL1 between patients with FDL and controls. BFL patients were removed to perform this analysis to avoid overestimation of the performance of these recombinant proteins. ROC analyses were also performed between FDL and BFL cases by removing controls, in order to highlight a threshold discriminating the cases of FDL and BFL
