  HAQ-DI: 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, 0 to 3: 0=no difficulty; 1=some difficulty;2=much difficulty; 3=unable to do. Overall score was computed as sum of domain sc ores and divided by number of domains answered. Total possible score range 0-3: 0=least difficulty and 3=extreme difficulty.
