From: Antibodies against the CB10 fragment of type II collagen in rheumatoid arthritis
Levels of antibodies against CB10 (a) and CB11 (b) of bovine type II collagen in patients with rheumatoid arthritis (RA; n = 96), psoriatic arthritis (PsA; n = 33), osteoarthritis (OA; n = 34) and in normal human serum (NHS; n = 93). The points represent, for individual sera, the number of standard deviations (SD) above the mean of normal sera, for which the mean is 0. A serum is regarded as positive if it is 3SD or more above the mean (dashed line).
