Increase in stiffness duration from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented improvement.

HAQ: participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3 where 0 = least difficulty and 3 = extreme difficulty.

Analysis population included all participants who were enrolled in the study. Here "N" (number of participants analyzed) signifies participants who were evaluable for this measure.

ROAD questionnaire: valid and responsive tool for measuring functional ability in RA participants. Consists of 12-items related to fine movements of upper extremity, locomotor activities of lower extremity, and activities that involve both upper and lower extremities. For each item participant rated the level of difficulty over the past week on a 5-point scale ranging from 0 (without any difficulty) to 4 (unable to do). Total ROAD score were transformed to a 0 to 10 point scale, where 0 = best status and 10 = poorest status.

SvH method included 16 areas for erosions and 15 areas for joint space narrowing (JSN) and subluxation/luxation in each hand, 6 areas for erosions and 6 areas for JSN and subluxation/luxation in each foot. Erosion per joint scored on 0-5 point scale; 0=normal joint to 5=complete collapse. Total erosion score for hands:0-160, for feet:0-120. JSN and subluxation/luxation scored on 0-4 point scale; 0=normal joint to 4= a bony ankylosis/a complete luxation of joint. Total JSN and subluxation/luxation score for hands:0-120, for feet:0-48. Total SvH score = 0-448; higher score=more erosion and JSN.
