Following publication of the original article [1], the authors identified errors in Fig. 1. The legends in Fig. 1c and d refer to placebo, baricitinib 4-mg and adalimumab treatment groups; the legends should refer to placebo, baricitinib 2-mg, and baricitinib 4-mg and the reference to these two studies in the figure caption are reversed. Additionally, the total number of interruptions for baricitinib 4-mg in RA-BEAM (Fig. 1b) has been corrected from 82 to 62 and the title for RA-BEAM has been corrected from 0-52 weeks to 0-24 weeks; labels have been corrected for MTX (8–14 days) in RA-BEGIN from 28 to 29 and for placebo (15–21 days) in RA-BUILD from 17 to 16.

The corrected Fig. 1 is given below.
