Participant Flow

Data of Iraq's participants aged greater than or equal to (\>=) 18 years, who received etanercept for at least 1 year, anytime from May 2012 through August 2019, for treatment of spondyloarthropathies (SpA) and met American College of Rheumatology/ European League Against Rheumatism (EULAR) 2019 criteria for SpA were included in the study.

Population: Analysis population included all participants whose data were included in the study for retrospective observation. Here, "number analyzed" signifies the number of participants evaluable at specific time points.

BASDAI is a set of 6 questions to determine disease activity in participant with SpA. Participants answered each 6 questions on a scale of 0 (no problem) to 10 (the worst problem). The BASDAI score is calculated by computing the mean of questions 5 and 6 and adding it to the sum of questions (Q) 1-4. This score is then divided by 5. BASDAI score = (Q1 + Q2 + Q3+ Q4+ \[Q5 + Q6/2\])/5. BASDAI score ranges from 0 (best) to 10 (worst), where higher scores meant worse condition. This outcome measure compared absolute BASDAI score between the participants who were adherent and not adherent to treatment. Comparison was done for 1 and 7 year adherence. For Year 1 adherence, last visit was Year 1 (Month 12). For Year 7 adherence last visit was Year 7.

BASFI is a set of 10 questions to determine degree of functional limitation in participants with SpA. Participants answered each 10 questions on a scale of 0 (no functional impairment) to 10 (maximal impairment). BASFI score was calculated as mean of scores from 10 questions. BASFI score ranged from 0 (no functional impairment) to 10 (maximal impairment), where higher scores meant worse condition. This outcome measure compared absolute BASFI score between the participants who were adherent and not adherent to treatment. Comparison was done for 1 and 7 year adherence. For Year 1 adherence, last visit was Year 1 (Month 12). For Year 7 adherence, last visit was Year 7.
