CDAI \<= 2.8 indicates disease remission, \>2.8 to 10 = low disease activity, \>10 to 22 = moderate disease activity, and \>22 = high disease activity.

SecondaryNumber of Participants With Disease Activity Status Based on DAS28 Score

Participants were assigned the disease activity status on the basis of DAS28 score. Description of DAS28 calculation is provided in Outcome Measure 7. Remission: DAS28 score \<= 2.6; low disease activity: DAS28 \<=3.2; moderate disease activity: DAS28 \<=5.1; and high disease activity: DAS28 \>5.1.
