Change in mTSS for RINVOQ + MTX vs placebo + MTX at Week 26 was a ranked secondary endpoint controlled for multiplicity. All other data shown for RINVOQ + MTX vs placebo + MTX were prespecified nonranked endpoints not controlled for multiplicity; nominal P-values are provided. No statistical comparisons were made between RINVOQ and adalimumab groups for radiographic endpoints.
*P≤0.001 vs placebo + MTX
† Indicates multiplicity-controlled comparison of RINVOQ + MTX vs placebo + MTX.
Treatment groups are by initial randomization. For the placebo group, all data at Week 48 were imputed by linear extrapolation. X-ray data collected at treatment switching or at discontinuation of placebo (for patients who discontinued placebo) were used for extrapolation. Specifically, for placebo patients who switched to RINVOQ at Week 26, the Week 26 x-ray was used for extrapolation to impute the data at Week 48. For patients randomized to RINVOQ or adalimumab who were rescued, data at Week 48 were also imputed by linear extrapolation using x-ray data collected at treatment switching.1-3
LS: least squares; mTSS: modified total Sharp score; MTX: methotrexate; MTX-IR: inadequate response to MTX.
