*p<0.05

**p<0.01, DAS28: 28-joint count disease activity score; ESR: erythrocyte sedimentation rate, CRP: C-reactive protein, CDAI: clinical disease activity index, S:surgery, NS: non-surgery, M = months, SD: standard deviation.

§ validated measures were unavailable in most patients, assessment was based on an agreed upon a priori protocol
