DAS28-4 (ESR) <= 3.2 implied low disease activity and >3.2 to 5.1 implied moderate to high disease activity, and DAS28-4 (ESR) <2.6 = remission.
  • Number of Participants With Disease Activity Score Based on 28-Joint Count and Erythrocyte Sedimentation Rate (4 Variables) (DAS28-4 [ESR]) Less Than 2.6 and Less Than or Equal to 3.2 at Month 6 [ Time Frame: Month 6 ] [ Designated as safety issue: No ]
    DAS28-4 (ESR) was calculated from SJC and TJC using 28 joints count, ESR (mm/hour) and PtGA of disease activity (participant rated arthritis activity assessment). Total score range: 0-9.4, higher score=more disease activity. DAS28-4 (ESR) <= 3.2 implied low disease activity and >3.2 to 5.1 implied moderate to high disease activity, and DAS28-4 (ESR) <2.6 = remission.
