Fig. 2From: Rheumatoid arthritis–associated autoantibodies in non–rheumatoid arthritis patients with mucosal inflammation: a case–control studySerum immunoglobulin G (IgG) (a) and IgA anti-cyclic arginine peptide (anti-CAP) (b) levels in healthy controls (HC) and in patients with periodontitis (PD), bronchiectasis (BR), cystic fibrosis (CF) and rheumatoid arthritis (RA). CAP represents the native counterpart of CCP. Cutoff values are indicated: >2 SD above the mean of HC. Bar indicates the median. *p < 0.05, **p < 0.01, Kruskal–Wallis one-way analysis of variance with Dunn’s multiple-comparisons post-test compared with HC if overall p < 0.05Back to article page
