RAID was a participant reported outcome measure used to evaluate the impact of RA on participant's quality of life which comprised 7 domains: • pain, • function, • fatigue, • physical and psychological well-being, • sleep disturbance, and • coping. Each domain was a single question scored on a 0 to 10 continuous NRS. The values for each of these domains were weighed by participant assessment of relative importance and combined in a single value. Total RAID score range was 0 (not affected, very good) to 10 (most affected), where higher value indicated worse status.

Analysis was performed on ITT population. Here, 'overall number of participants analyzed' = participants evaluable for this outcome measure.

HADS questionnaire measures the presence and severity of anxiety and depression in both hospital and community settings. The questionnaire comprised of 14 items divided into 2 subscales: 7 items for anxiety subscale (HADS-A) and 7 items for depression subscale (HADS-D). Each item was scored on a 0 to 3 rating scale. The anxiety and depression subscales each ranged from 0 to 21 (0-7: normal, 8-10: borderline abnormal and 11-21: abnormal), where higher scores indicated greater severity of anxiety/depression. The subscales were independent for each result of depression and anxiety.

MAThyS was a multi-dimensional self-administered questionnaire comprised of five dimensions (emotional reactivity, cognition speed, psychomotor function, motivation and sensory perception) divided into 20 items relating to individual states as perceived by participants for the preceding week (at each specified Week). Each item was measured on a visual analog scale (VAS; in centimeters [cm]) ranged from 0 (inhibition of the state evaluated by the item) to 10 (excitation for the evaluated state). Total MAThyS score was sum of the 20 items and that might vary from score range 0 to 200 with lower scores indicated general inhibition and higher scores indicated general excitation.

FACIT-F was a 13-item questionnaire that assess fatigue in participants under chronic illness therapy. Participants scored each item on a 5-point Likert scale ranged from 0 to 4 (0 = not at all; 1 = a little bit; 2 = somewhat; 3 = quite a bit; 4 = very much). The scores of each item were reversed during score calculations, so that higher score values indicated more favorable conditions. Total score was the sum of score from each item and resulted in a score range from 0 to 52, with higher score indicated better participant health status (lower level of fatigue).

HAQ-DI was a participant-oriented questionnaire developed specifically to assess the extent of a RA participant's functional ability. It consisted of at least 2 or 3 questions per category, 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 (at each specified visit) rated on a 4-point scale where 0 = no difficulty; 1 = some difficulty; 2 = much difficulty; 3 = unable to do. Overall score was computed as the sum of category scores and divided by the number of categories answered, and ranged from 0 to 3, where 0 = no disability and 3 = completely disabled, higher score indicated more disability.

Duration of morning stiffness was defined as the time elapsed (in minutes) between the time of usual awakening (even if not in the morning) and the time the participant was able to resume normal activities without stiffness. At each specified time point, duration of morning stiffness was reported by the participant during the visit.

IPAQ was a 27-item self-reported questionnaire designed to measure physical activity of participant. The score was reported in metabolic equivalent (MET)-minutes per week. MET minutes represented the amount of energy expended to carry out physical activity. For IPAQ total score, the minimum value is zero and there is no maximum. Higher scores mean better levels of physical activity.
