The Disease Activity Score 28 is a validated index of rheumatoid arthritis disease activity. Twenty-eight tender joint counts, 28 swollen joint counts, the erythrocyte sedimentation rate (ESR), and the patient's assessment of global disease activity (on a visual analog scale [VAS] from 0 to 10 cm) are included in the DAS28 score. If the ESR value is missing, the C-reactive protein (CRP) value can be substituted. Scores on the DAS28 range from 0 to 10; higher scores indicate more disease activity. A DAS28 score >5.1 indicates high disease activity, a DAS28 score <3.2 indicates low disease activity, and a DAS28 score <2.6 indicates clinical remission.

Full analysis set (FAS). Participants with inadequate data or who met other exclusion criteria were not included in the FAS. "n" indicates the number of participants with available data at each time point.

Clinical remission is defined as a disease activity score (DAS) 28 score of < 2.6. The DAS28 is a validated index of rheumatoid arthritis disease activity. Twenty-eight tender joint counts, 28 swollen joint counts, the erythrocyte sedimentation rate (ESR), and the patient's assessment of global disease activity (assessed on a visual analog scale [VAS] from 0 to 10 cm) are included in the DAS28. If the ESR value is missing, the C-reactive protein (CRP) value can be substituted. Scores on the DAS28 range from 0 to 10; higher scores indicate more disease activity.

Significant therapeutic response was determined by DAS28 critical difference (Dcrit). A Dcrit response is a statistically determined value that exceeds the threshold of random fluctuation and signifies a positive individual response during treatment. A DAS28-Dcrit individual therapeutic response is defined as a decrease (improvement) in DAS28 from Baseline of ≥ 1.8.

Low disease activity is defined as a DAS28 score ≤ 3.2; Moderate disease activity as a DAS28 >3.2 to ≤5.1; High disease activity as a DAS28 >5.1.

Erythrocyte sedimentation rate (ESR) indirectly measures how much inflammation is in the body. A higher ESR is indicative of increased inflammation.

C-Reactive Protein (CRP) was measured from blood samples as a marker for inflammation. Higher levels are indicative of more inflammation. Normal concentration in healthy human serum is usually lower than 10 mg/L, slightly increasing with age.

Twenty-eight joints were assessed and classified as tender/not tender by pressure and joint manipulation on physical examination.

Twenty-eight joints were assessed and classified as swollen/not swollen by pressure and joint manipulation on physical examination.

A self-administered patient questionnaire used to assess patient function based on 18 questions. The numerically coded responses to the questions are added to provide a total patient score. The FFbH was calculated from this patient score by the following formula:

FFbH = (patient score x 100) ÷ 2 (number of valid responses). The resulting FFbH score reflects the degree of remaining functional capacity where 0 indicates maximal impairment and 100 indicates maximal functional capacity.

Participants indicated their global assessment of disease activity over the last 7 days on a visual analog scale (VAS) from 0 (best) to 10 (worst) cm; lower scores indicate better patient status.

Participants indicated their level of fatigue over the last 7 days on a visual analog scale (VAS) from 0 (best) to 10 (worst) cm; lower scores indicate better patient status.
