Correlation of anti-CCP activity radiographic joint destruction. Shown is the subset analysis of anti-CCP reactivity and radiographic presence of erosion in patients with rheumatoid arthritis (RA), juvenile rheumatoid arthritis (JRA), psoriatic arthritis (PsA), and inflammatory arthritis. (No (%))
| RA (n=82) | PsA (n=16) | JRA (n=19) | Inflammatory arthritis (n=12) | |
|---|---|---|---|---|
| Erosion + | (n=52) | (n=5) | (n=15) | (n=6) |
| CCP + | 42 (81) | 1 (20) | 6 (40) | 0 (0) |
| CCP − | 10 (19) | 4 (80) | 9 (60) | 6 (100) |
| Erosion − | (n=30) | (n=11) | (n=4) | (n=6) |
| CCP + | 16 (53) | 1 (9) | 0 (0) | 1 (17) |
