Figure 3From: Class-switched B cells display response to therapeutic B-cell depletion in rheumatoid arthritisAntibody concentrations. Course of (a) rheumatoid factor (RF), (b) cyclic citrullinated peptide (CCP) antibodies, and (c) total immunoglobulin IgG, IgA, and IgM serum concentrations after therapeutic B-cell depletion in good responders (continuous line) and in non-responders or moderate responders (designated as other patients, dotted line). Asterisks indicate statistically significant differences (P < 0.05) between these two patient groups.Back to article page
