a The proportion of disease activity at 24 weeks after the initiation of tofacitinib treatment with or without a concomitant use of MTX. b The proportion of disease activity at 24 weeks after the initiation of baricitinib treatment with or without a concomitant use of MTX. Disease activity was categorized as follows. DAS 28-ESR < 2.6 (remission), 2.6 to < 3.2 (LDA), 3.2–5.1 (MDA), > 5.1 (HDA). MTX methotrexate, LOCF last observation carried forward, ESR erythrocyte sedimentation rate, DAS disease activity score, LDA low disease activity, MDA moderate disease activity, HDA high disease activity
