ASDAS(CRP) was derived using BASDAI (6-item questionnaire measures disease activity on a scale of 0 \[none\] to 10 \[severe\], higher score=more disease activity) and PGA (measure disease activity on a scale of 0 \[not active\] to 10 \[very active\], high score=more disease activity) and calculated by using the following formula, 0.121 x Back Pain (Q2 of BASDAI) + 0.058 x Duration of Morning Stiffness (Q6 of BASDAI) + 0.110 x PGA + 0.073 x Peripheral Pain/Swelling (Q3 of BASDAI) + 0.579 x Ln(high sensitivity \[hs\] CRP mg/Liter \[L\] + 1). If hsCRP values were smaller than 2 mg/L, they were set to 2 mg/L in the formula. The range of score was \>= 0.636 to no defined upper limit. A negative change from baseline value indicates decrease in disease activity; a positive change from baseline value indicates increase in disease activity.

SF-36 v.2 (Acute): 36-item generic health status measure. It measured 8 general health domains: physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, mental health. These domains were aggregated into 2 summary scores - physical component summary (PCS), mental component summary (MCS). Four domains comprised PCS score (physical functioning, role-physical, bodily pain, general health) and remaining 4 domains comprised MCS score (vitality, social functioning, role-emotional, mental health). Normalized domain scores, PCS, MCS scores are used in analyses. Component and domain scores were scored by using United States 1998 general population norm. Resulting norm-based T-scores for both the SF36 version 2 and SF36 health domain scale and component summary measures had means of 50 and standard deviations of 10. Higher PCS/MCS/domain score represent better health status.

BASMI assess axial status and spinal mobility. It composed of 5 clinical measures: lateral spinal flexion, tragus-to-wall distance, lumbar flexion (modified Schober), maximal intermalleolar distance, cervical rotation. BASMI - Linear Method score was average of 5 individual component score mapped between 0 and 10, high score=more impairment of axial status, spinal mobility. For cervical rotation angle, participant sit straight on chair with chin level and hands on knees. Blinded assessor place goniometer at top of head in line with nose and ask participant to rotate neck maximally to left, follows with goniometer and record angle between sagittal plane and new plane after rotation. A second reading obtained and both readings recorded. Procedure repeated for right side. Better of two for each side was selected for scoring. Scoring done by calculating mean of left and right measurement and recorded in degrees (range: 0 to 90), higher cervical rotation value=better health status.

The BASDAI was a validated questionnaire that consisted of 6 questions pertaining to the 5 major symptoms of AS: fatigue; spinal pain; peripheral arthritis; enthesitis, intensity of morning stiffness and duration of morning stiffness. Each question was rated using a numerical rating scale from 0 (none) to 10 (very severe), higher score=high disease activity. The BASDAI score was calculated by computing the mean of questions 5 and 6 and adding it to the sum of questions 1 to 4. This score was then divided by 5. The total BASDAI score was ranged from 0= none to 10= very severe, where higher score indicated high disease activity. BASDAI inflammation score was derived by taking mean of the responses of question 5 and 6 and ranged from 0 (none) to 10 (very severe), where higher score indicated more inflammation (morning stiffness).

Chest expansion (measured in centimeters (cm), is defined as the difference in the thoracic circumference during full expiration versus full inspiration. This was measured at the 4th intercostal space. The difference between maximal inspiration and expiration of the two attempts was recorded. The better of the two attempts was used to calculate chest expansion which was defined to be greater than or equal to 0 cm with no defined maximum/upper limit. Greater chest circumference corresponds to higher score indicated more spinal mobility/better health status (measured as Chest Expansion in cm).
