The HUI-3 is a generic approach to the measurement of health status and assessment of HRQL. The HUI-3 was comprised of two complementary components. The first component was a multi-attribute health status classification system that was used to describe health status. The second component was a multi-attribute utility function that was used to value health status as measured within the corresponding multi-attribute health status classification system. An increase in the HUI-3 score represents improvement.	Weeks 24, 52, 104, 128, 156, 180, 208, 232, and 260
Mean Change in the Ankylosing Spondylitis Quality of Life Questionaire (ASQoL) in Subjects Through Week 260 of Adalimumab Exposure	ASQoL determined subject's quality of life and is comprised of 18 questions (yes or no) to be completed by the subject. Each statement on the ASQoL is given a score of "1" or "0." All item scores were summed to give a total score or index. Total scores ranged from 0 (good quality of life) to 18 (poor quality of life) related to ability to cope, relationships, mood, sleep, motivation, activities of everyday living, independence, and social life. Decrease in ASQoL score represents improvement.	Baseline and at Weeks 12, 24, 52, 76, 104, 128, 156, 180, 208, 232, and 260
Number of Subjects With Ankylosing Spondylitis Quality of Life Questionaire (ASQoL) MCID Response (MCID <= -1.8 Points) Through Week 260 of Adalimumab Exposure	ASQoL determined subject's quality of life comprised of 18 questions to be completed by the subject. Each statement on the ASQoL is given a score of "1" or "0." All item scores were summed to give a total score. Total scores ranged from 0 (good quality of life) to 18 (poor quality of life) related to ability to cope, relationships, mood, sleep, motivation, activities of everyday living, independence, and social life. Decrease in ASQoL score represents improvement. Responders are subjects with MCID <= -1.8 points. MCID was determined by a >= 1.8 score decrease during exposure to adalimumab.	Weeks 12, 24, 52, 76, 104, 128, 156, 180, 208, 232, and 260
Number of Subjects Achieving the Patient Acceptable Symptoms State Through Week 260 of Adalimumab Exposure	Completed by subject at each visit. The MCIS was a patient reported outcome where the subjects were expected to respond (yes/no) to the following question: Considering all the different ways your disease is affecting you, if you would stay in this state for the next months, do you consider that your current state is satisfactory? An increase in PASS indicates improvement. During earlier weeks of the study PASS was measured/reported as minimal clinically important state (MCIS).	Weeks 12, 24, 52, 76, 104, 128, 156, 180, 208, 232, and 260
Mean Change From Baseline in Serum Matrix Metalloproteinase-3 (MMP-3) in Subjects Treated With Any Dose of Adalimumab Through Week 260 of Adalimumab Exposure	Cartilage and bone degradation were assessed by evaluating changes in MMP-3. A decrease in MMP-3 represents improvement.	Weeks 12, 24, 52, 76, 104, 128, 156, 180, 208, 220, 232, 244, and 260
Mean Change From Baseline in Urine Type II Collagen C Telopeptide (CTX-II) in Subjects Treated With Any Dose of Adalimumab Through Week 260 of Adalimumab Exposure	Cartilage and bone degradation were assessed by evaluating changes in CTX-II. A decrease in CTX-II represents improvement.	Weeks 12, 24, 52, 76, 104, 128, 156, 180, 208, 220, 232, 244, and 260
Mean Change From Baseline in Serum Type I Collagen N-telopeptide (NTx) in Subjects Treated With Any Dose of Adalimumab Through Week 260 of Adalimumab Exposure	Cartilage degradation and bone resorption were assessed by evaluating changes in NTx. A decrease in NTx represents improvement.	Weeks 12, 24, 52, 76, 104, 128, 156, 180, 208, 220, 232, 244, and 260
Mean Change in Spinal Spondyloarthritis Research Consortium of Canada (S.P.A.R.C.C.) Magnetic Resonance Imaging (MRI) Index of Disease Activity Score at Weeks 12 and 52 of Adalimumab Exposure	The S.P.A.R.C.C. MRI index is a tool for scoring inflammation and structural damage in both the spine and sacroiliac (SI) joints. The spinal SPARCC index score consists of 3 subscales (edema, intense edema, and deep edema). Edema was defined as the presence of increased STIR signal in each of 4 Discovertebral unit (DVU) quadrants and was assigned a score (0 = normal signal, 1 = increased signal). The scoring of edema was repeated for each of 3 consecutive sagittal slices with a maximum score of 12 per DVU (range for edema, 0-72). The total spinal SPARCC index score is 0 to 108.	Week 12 and Week 52
Mean Change in Sacroiliac (SI) Spondyloarthritis Research Consortium of Canada (S.P.A.R.C.C.) Magnetic Resonance Imaging (MRI) Index of Disease Activity Score at Weeks 12 and 52 of Adalimumab Exposure	The S.P.A.R.C.C. MRI index is a tool for scoring inflammation and structural damage in both the spine and sacroiliac (SI) joints. The spinal SPARCC index score consists of 3 subscales (edema, intense edema, and deep edema). Edema was defined as the presence of increased STIR signal in each of 4 Discovertebral unit (DVU) quadrants and was assigned a score (0 = normal signal, 1 = increased signal). The scoring of edema was repeated for each of 3 consecutive sagittal slices with a maximum score of 12 per DVU (range for edema, 0-72). The total spinal SPARCC index score is 0 to 108.	Weeks 12 and 52
