Fig. 3From: Circulating secretory IgA antibodies against cyclic citrullinated peptides in early rheumatoid arthritis associate with inflammatory activity and smokingThree-year disease course of early rheumatoid arthritis in relation to secretory immunoglobulin A (SIgA) anti-cyclic citrullinated peptide (anti-CCP) antibody status as mirrored by (a) erythrocyte sedimentation rate (ESR), (b) C-reactive protein (CRP), (c) 28-joint Disease Activity Score (DAS28), (d) swollen joint count, and (e) tender joint count. Mean values are shown, and p values refer to differences in AUCBack to article page
