Changes in SIJs and spine MRI and CRP values in patients initially receiving placebo
| Baseline status | Status post-baseline through week 12, n (%) | |||
|---|---|---|---|---|
| CRP elevated | MRI+ | MRI+ and/or CRP elevated | MRI– and CRP normal | |
| MRI– and CRP normal (n = 20) | 4 (20.0) | 8 (40.0) | 10 (50.0) | 10 (50.0) |
| MRI+ and/or CRP elevated (n = 73) | 44 (60.3) | 51 (69.9) | 67 (91.8) | 6 (8.2) |
| Both MRI+ and CRP elevated (n = 25) | 24 (96.0) | 19 (76.0) | 25 (100) | 0 |
| MRI+ only (n = 61) | 34 (55.7) | 48 (78.7) | 56 (91.8) | 5 (8.2) |
| CRP elevated only (n = 37) | 34 (91.9) | 22 (59.5) | 36 (97.3) | 1 (2.7) |
Patients received placebo for 12 weeks. MRI status is for the SIJ and/or the spine. MRI+: positive MRI; MRI−: normal MRI.
