Figure 1.

Effectiveness and drug retention rates of tofacitinib and abatacept. (A) After adjustments with IPTW, DAS28-ESR between the two groups was compared at each time point. Error bars indicate 95% CIs. *P <0.05, ^¶p <0.01 by Student’s t-test. (B) The rates of remission and achievement of LDA in DAS28-ESR at week 52 were compared between the two groups by Pearson’s χ² test. (C) Drug retention rates in both groups are shown over 52 weeks (Kaplan–Meier curves). ABT: abatacept; DAS28-ESR: DAS in 28 joints using the ESR; IPTW: inverse probability of treatment weighting; LDA: low disease activity; TOF: tofacitinib
