Primary	Change in Synovitis Measured by Outcome Measures in Rheumatoid Arthritis Clinical Trials (OMERACT) Rheumatoid Arthritis Magnetic Resonance Image Scoring System (RAMRIS) Score at Week 16 Compared to Baseline for Certolizumab Pegol Arm	Rheumatoid Arthritis Magnetic Resonance Image Scoring System (RAMRIS): Synovitis is defined as an area in the synovial compartment that shows above normal postgadolinium enhancement of a thickness greater than the width of the normal synovium. T1-weighted images were acquired before and after the administration of intravenous contrast agent containing gadolinium. Intravenous contrast was required to demonstrate enhancing synovitis. Synovitis was scored 0 to 3 in 3 wrist regions and in each of the second through fifth metacarpophalangeal (MCP) joints. A score of 0 is normal, with no enhancement or enhancement up to the thickness of normal synovium, while scores of 1 to 3 (mild, moderate, severe) refer to increments of one-third of the presumed maximum volume of enhancing tissue in the synovial compartment. Total synovitis score ranges from a minimum of 0 to a maximum of 21. A negative value in synovitis change from Baseline score indicates an improvement.	From Baseline to Week 16	No

Secondary	Change From Baseline to Week 16 in Health Assessment Questionnaire - Disability Index (HAQ-DI)	The Health Assessment Questionnaire-Disability Index (HAQ-DI) is a subject reported questionnaire that provides an assessment of the impact of the disease and its treatment on physical function. The HAQ-DI assesses the degree of difficulty experienced in 8 domains of daily living activities using 20 questions. The domains are dressing and grooming, arising, eating, walking, hygiene, reach, grip, and common daily activities, and each domain (activity) consists of 2 or 3 items. For each question the level of difficulty is scored from 0 to 3 where 0 = no difficulty, 1 = some difficulty, 2 = much difficulty and 3 = unable to do. A total score is computed from the item scores using the scoring rules provided by the author (Fries, 1980). The total score ranges from 0 to 3 with lower scores meaning lower disability. A negative value in HAQ-DI change from Baseline indicates an improvement.	From Baseline to Week 16	No
