Measure Type	Secondary
Measure Title	Health Assessment Questionnaire Disability Index (HAQ-DI) at Month 4, 5 and 6
Measure Description	HAQ-DI: participant-reported assessment of ability to perform tasks in 8 functional 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, 0=least functional difficulty and 3=extreme functional difficulty.
Time Frame	Month 4, 5, 6
Safety Issue	No
