CD40LG and rheumatoid arthritis: Levels of IgM against CFAH1211−1230 HNE in RA patients were greatly higher than the levels in HCs by 1.40-fold (p = 0.0002, Fig. 3d, left panel), and AUC values were 0.70 (with 85.0% sensitivity and 41.7% specificity) and 0.59 (with 80.0% sensitivity and 36.7% specificity) for detecting patients with OA and RA (Table 2).
