Arthritis Impact Measurement Scale - Version 2 (AIMS2) Main Component Score at Baseline

AIMS2 is a disease-specific measure of physical, social, and emotional well-being. It is a 78-item questionnaire assessing 12 scales: moving capacities, walking and dexterity, hand and fingers movements, arm movements, self-care, household activities, social activities, support of family and friends, joint pain, work, nervous tension and psychological condition (anxiety and depression). Each item was scored as 0 (or 1, best situation) to 4 (worst situation). Sub-total score of each of the 12 scales normalized to a maximum of 10. Total score were calculated for AIMS2 Affect ([Level of tension + Mood]/2), AIMS2 Physical ([Mobility level + Walking and bending + Hand and finger function + Arm function + Self Care + Household tasks]/6), and AIMS2 Symptom (Arthritis pain) with total score range from 0 to 10 for all component scores, where higher scores indicated worse situation.

Visual Analog Scale (VAS) Fatigue Score

Participants recorded their fatigue score on a range of 0 to 10, where higher score indicated higher intensity of fatigue.

Disease Activity Score Based on 28-Joints Count and Erythrocyte Sedimentation Rate (DAS 28-ESR)

DAS28-ESR was calculated from the number of swollen joints (SJC) and tender joints (TJC ) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (millimeter per hour [mm/hour]) and participant's assessment of disease activity visual analog scale (scores ranging 0 [very well] to 100 mm [extremely bad]). Total score range: 0-10, higher score=more disease activity (DA). DAS28-ESR less than equal to (<=) 3.2 = low disease activity, DAS28 greater than (>) 3.2 to 5.1 = moderate to high DA

Disease Activity Score Based on 28-Joints Count and C-Reactive Protein (DAS 28-CRP)

DAS28-CRP was calculated from the number of swollen joints ( SJC) and tender joints (TJC) count using 28 joint count and CRP (milligram per liter [mg/L]). Total score range: 0-10, higher score= more disease activity. DAS28 (CRP) : <3.2= low disease activity, >3.2 to 5.1 = moderate to high disease activity and less than (<)2.6 = remission.

Health Assessment Questionnaire (HAQ) Total Score

HAQ: 20-item 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. Each item scored on 4-point scale, 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as sum of item scores. HAQ total score was 0 to 60 (as used in Belgium), where greater score indicated greater difficulty.
