Data for European and Japanese regions were reported.

Title
Number of Participants With Change in Methotrexate (MTX) and Corticosteroid (CST) Dose
Description
Participants received MTX at stable and tolerated dose during baseline were categorized as "low dose (<12.5 mg per week [mg/wk])", "medium dose (>=12.5 - <20 mg/wk)", and "high dose (>=20 mg/wk)". Participants received oral CST at stable dose during baseline were categorized as "low dose (<5 mg/day)", and "high dose (>=5 mg/day)". Change in MTX and CST dose from baseline between Day 1-85 and Day 86-169 were categorized as follows: 'Increased', 'no change' and 'decreased'. Participants were counted once with dose increases counted first, followed by no change and then dose decreases.
