Error bars represent 95% CI. *Includes patients receiving abatacept as a second- or further-line of treatment. CDAI, Clinical Disease Activity Index; CI, confidence interval; CRP, C-reactive protein; DAS28, 28-item Disease Activity Score; ESR, erythrocyte sedimentation rate; LDAS, low disease activity state.
