Mean and Std. Dev. for MRI disease activity RAMRIS scores over 1 year. The mean total radiographic score change is also shown.

Synovitis (0–9)	5.8 ± 1.9	5.8 ± 2.7	5.3 ± 2.9	5.2 ± 1.8	5.1 ± 1.7
Erosions (0–150)	10.7 ± 13.9	11.1 ± 17.2	14.5 ± 16.9	11.7 ± 15.1	13.1 ± 16.8
BME (0–45)	7.4 ± 9.5	6.9 ± 8.7	7.1 ± 8.5	5.8 ± 7.6	7.8 ± 8.0
Total X-ray score (max 448)	33.6	—	34.4	34.7	35.4

Erosions score excluded a patient with complete fused carpal joints.
