ACR20/50/70, defined as ≥20 percent (%), 50%, or 70% improvement, respectively, compared to baseline in tender joint count (TJC) and swollen joint count (SJC), and 20%/50%/70% improvement in at least 3 of 5 additional ACR core set variables: Patient Assessment of Pain; Patient's Global Assessment of Disease Activity; Physician's Global Assessment of Disease Activity; Health Assessment Questionnaire - Disability Index (HAQ-DI); and an acute phase reactant (erythrocyte sedimentation rate [ESR] or C-Reactive Protein [CRP]). If CRP was missing or not done, then ESR was used.

Complete clinical response was defined as having an ACR70 for at least 13 weeks.

ACR20/50/70, defined as ≥20%, 50%, or 70% improvement, respectively, compared to baseline in TJC and SJC, and 20%/50%/70% improvement in at least 3 of 5 additional ACR core set variables: Patient Assessment of Pain; Patient's Global Assessment of Disease Activity; Physician's Global Assessment of Disease Activity; HAQ-DI; and an acute phase reactant (ESR or CRP). If CRP was missing or not done, then ESR was used.

Complete clinical response was defined as having an ACR70 for at least 13 weeks.

The EULAR response criteria were based on the assessment of disease activity using the DAS28. The EULAR response criteria included not only change in disease activity but current disease activity. To be classified as responders, participants had to have a significant change in DAS28 and a low current disease activity. There were 4 categories of EULAR response rates: good, moderate, good/moderate, and none. The DAS28 scoring used 4 core components: SJC, TJC, Patient's Global Assessment of Disease Activity, and ESR. The DAS28 has a continuous scale ranging from 0 to 9.4. The level of disease activity was interpreted as low (DAS28 score less than or equal to [≤]3.2), moderate (DAS28 score greater than [>]3.2 but ≤5.1), or high (DAS28 score >5.1). A DAS28 score <2.6 corresponded to a state of remission according to American Rheumatism Association criteria.

A change of 1.2 units in DAS28 in an individual participant was considered a significant change.

Joints assessed for swelling consisted of shoulders, elbows, wrists, interphalangeal (digit 1), distal interphalangeal joints (digits 2-5), proximal interphalangeal joints (digits 2-5), metacarpophalangeal joints (digits 1-5), and knees.

Physician Global Assessment of Disease Activity was measured using a 100-mm visual analog scale (VAS) where the extreme left end of the line was 0 = no disease activity and the extreme right end of the line was 100 = maximum disease activity. The physician marked the line and the distance from the left edge was measured in mm.

Patient Global Assessment of Pain was measured using a 100-mm VAS where the extreme left end of the line was 0 = no pain and the extreme right end of the line was 100 = unbearable pain. The participant was asked to mark the line and the distance from the left edge was measured in mm.

HAQ-DI: 20 questions, 8 categories of functioning: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and common usual activities. Participants report amount of difficulty in performing 2-3 specific subcategory items. Difficulty score is from 0 to 3 (0 = without any difficulty; 1 = with some difficulty; 2 = with much difficulty; and 3 = unable to do). The highest component score in each of the 8 categories determined the score for that category, unless aids, devices, and/or help from another person were required which = a score of 2 (unless already 2 or 3). The 8 category scores were averaged into overall HAQ-DI score ranging from 0 to 3 (0 to 1 = mild to moderate difficulty; 1 to 2 = moderate to severe disability; and 2 to 3 = severe to very severe disability). HAQ-DI not computed if > 2 categories were missing.

ESR was measured in mm/hour and was used to determine the acute phase response. Lower ESR values indicate reduction in disease activity; normal reference range: 0-20 mm/hr.

CRP levels were measured in milligrams/liter (mg/L) and were used to determine the acute phase response. A reduction in CRP levels is considered an improvement; normal reference range ≤10 mg/L.

Participant fatigue was evaluated using the FACIT-F scale, a 13-item questionnaire in which the participants were requested to score each item on a 5-point scale. The FACIT-F scores ranged from 0 to 52, with higher scores representing less fatigue. Score changes of 4 points or more were considered clinically meaningful. The total score was a summation of all 13 items, where 2 of the positive items (I have energy; I am able to do my usual activities) were reversed for scoring.
