Participant Flow
This is a multicenter, non-interventional (NI) study conducted to evaluate data collected from a cross sectional population of participants with rheumatoid arthritis (RA) who received treatment with etanercept, adalimumab, or infliximab for a minimum of 6 months and maximum of 24 months prior to the study assessment visit.
Participants treated with one of the three targeted therapies were enrolled using interactive response technology to assure data for approximately 200 participants were included for each RA treatment.

The DAS28 assessment is a derived measurement with differential weight given to each component. DAS28 will be calculated twice, utilizing first ESR, and then CRP as the acute phase reactant: 1) DAS28-ESR = 0.56 sqrt (28 painful/tender joint count) + 0.28 sqrt (28 swollen joint count) + 0.70 (ln ESR) + 0.014 GH, where GH=subject general health VAS (0-100 mm). 2) DAS28-4 CRP = 0.56 sqrt (28 painful/tender joint count) + 0.28 sqrt (28 swollen count) + 0.36 (ln CRP+1) + 0.014 GH + 0.96, where GH=subject general health VAS (0- 100 mm), higher scores were indicative of a worse outcome. The specific components of the DAS28 assessment that were used in this study are: Tender/Painful Joint Count (28), Swollen Joint Count (28), ESR/CRP, and Subject's General Health VAS assessment.

The HAQ-DI assesses the degree of difficulty a participant has experienced during the past week in 8 domains of daily living activities: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and other activities. Each activity category consists of 2-3 items. For each question in the questionnaire, the level of difficulty is scored from 0 to 3 with 0 representing "no difficulty," 1 as "some difficulty," 2 as "much difficulty," and 3 as "unable to do." Any activity that requires assistance from another individual or requires the use of an assistive device adjusts to a minimum score of 2 to represent a more limited functional status. The total score range for the HAQ-DI scale, minimum score was 0 (best), maximum score was 3 (worst).
