ACR responses are assessed with a composite rating scale of the American College of Rheumatology that includes 7 variables: tender joint count (TJC); swollen joint count (SJC); levels of an acute phase reactant (C-reactive Protein levels [CRP]); participant's assessment of pain; participant's global assessment of disease activity; physician's global assessment of disease activity; participant's assessment of physical function by (health assessment questionnaire disability index [HAQ-DI]). ACR20 is defined as achieving at least 20% improvement in both TJC and SJC, and at least 20% improvement in at least 3 of the 5 other assessments of the ACR.

Physical function was assessed by HAQ-DI. It consisted of at least 2 questions per category, participant reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week rated on a 4-point scale where 0 = no difficulty; 1 = some difficulty; 2 = much difficulty; 3 = unable to do. Overall score was computed as the sum of category scores and divided by the number of categories answered, ranging from 0 to 3, where 0 = no disability and 3 = unable to do, high-dependency disability. Least-squares (LS) means and standard errors (SE) at Week 12 were obtained from a mixed-effect model with repeated measures (MMRM) with treatment, region, number of previous anti-TNFs, visit, and treatment-by-visit interaction as fixed effects and baseline HAQ-DI as a covariate.

Marker of inflammation assessed by the high sensitivity C-reactive protein (hs-CRP) in mg/L. The DAS28 score provides a number indicating the current disease activity of the RA. DAS28 total score ranges from 2-10. A DAS28 score above 5.1 means high disease activity, whereas a DAS28 score below 3.2 indicates low disease activity and a DAS28 score below 2.6 means disease remission. LS means and SE at Week 24 were obtained from a MMRM with treatment, region, number of previous anti-TNFs, visit, and treatment-by-visit interaction as fixed effects and baseline DAS28-CRP score as a covariate.

SF-36 is a generic 36-item questionnaire measuring health-related quality of life (HRQL) covering 2 summary measures: PCS and mental component summary (MCS). The SF-36 consists of 8 subscales. The PCS had 4 subscales: physical function, role limitations due to physical problems, pain, and general health perception. The MCS had 4 subscales: vitality, social function, role limitations due to emotional problems, and mental health. Participants self-report on items in a subscale that have between 2-6 choices per item using Likert-type responses (e.g. none of the time, some of the time, etc.). Summations of item scores of the same subscale give the subscale scores, which are transformed into a range from 0 to 100; 0= worst HRQL, 100=best HRQL. Higher scores indicate better health and well-being.
