DAS28 was a measure of disease activity in participants with rheumatoid arthritis. DAS28 was calculated from swollen joint count (SJC) and tender/painful joint count (TJC) using 28 joints count, C-reactive protein (CRP) (milligrams per liter [mg/L]) or erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hr]) levels and patient global assessment (PGA) of disease activity on a 0-100 mm scale (scores ranging from 0 mm [very well] to 100 mm [extremely bad], higher scores indicated worst health condition). DAS28 score range from 0 (none) to 9.4 (extreme disease activity). DAS28 [less than or equal to] <=3.2 implied low disease activity and greater than (>) 3.2 to <=5.1 implied moderate disease activity, >5.1 implied high disease activity, and DAS28 less than (<) 2.6 implied remission.
