ListOutcomeTime frameDescription
PrimaryPercentage of Participants With 7 Years Adherence to Etanercept7 years [from the data retrieved and observed in 1 month of this study]In this outcome measure, percentage of participants who continued etanercept treatment and adhered to the treatment for 7 years were reported.
OtherAbsolute Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Score at Baseline and Last Visit: Participants Adherent and Not Adherent to TreatmentYear 1 adherence: Baseline (pre-treatment), Year 1; Year 7 adherence: Baseline (pre-treatment), Year 7 [from the data retrieved and observed in 1 month of this study]
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.
OtherChange From Baseline in BASDAI Score at Last Visit: Participants Adherent and Not Adherent to TreatmentYear 1 adherence: Baseline (pre-treatment), Year 1; Year 7 adherence: Baseline (pre-treatment), Year 7 [from the data retrieved and observed in 1 month of this study]

This outcome measure compared change from baseline in BASDAI score at last visit 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.
OtherAbsolute Bath Ankylosing Spondylitis Functional Index (BASFI) Score at Baseline and Last Visit: Participants Adherent and Not Adherent to TreatmentYear 1 adherence: Baseline (pre-treatment), Year 1; Year 7 adherence: Baseline (pre-treatment), Year 7 [from the data retrieved and observed in 1 month of this study]
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.
