Disease activity scores in DAS28-ESR, CDAI, and SDAI. Mean disease activity scores and mean changes from baseline scores in DAS28-ESR (A), CDAI (B), and SDAI (C) recorded over 24 weeks are shown after the initiation of treatment with tofacitinib or abatacept. RA disease activity scores between the two treatment groups were compared at each time point. Error bars indicate 95% confidence intervals. *p < 0.05 by the Student’s t test. CDAI, Clinical Disease Activity Index; DAS28-ESR, Disease Activity Score in 28 joints using the erythrocyte sedimentation rate: SDAI, Simplified Disease Activity Index
