van der Heijde D, Schiff M, Tanaka Y, et al. Low rates of radiographic progression of structural joint damage over 2 years of baricitinib treatment in patients with rheumatoid arthritis. RMD Open 2019;5:e000898. doi: 10.1136/rmdopen-2019-000898
The authors want to alert readers to the following errors in regard to Figure 3.
In panels A (mTSS) and B (ES) for the RA-BEGIN graphs, the symbol (‡) indicating the significance level for the comparison between the baricitinib 4-mg and baricitinib 4-mg plus MTX treatment groups (denoting p≤0.05) should be over the 1 year time point, not the 2 year time point in both graphs.
In panel A (mTSS) for RA-BEAM, for the adalimumab versus placebo comparison at 2 years, the significance should have been shown as ++ (p≤0.01) and not +++ (p≤0.001).
In the Results text, p.8, line 12 (relating to Figure 3, panel A) ‘…baricitinib treatment groups (0.21±0.01…’ should read: ‘…baricitinib treatment groups (0.21±0.10…’
