The domains of the HAQ-DI are dressing and grooming, arising, eating, walking, hygiene, reach, grip and common daily activities. The total score ranges from 0 to 3 with lower scores meaning lower disability. The change from baseline of HAQ-DI, minimum is -3, the maximum is 3. higher scores mean a worse outcome.

SECONDARY outcome

Timeframe: week 24

In the last month, number of work days missed, number of work days with reduced productivity. In the last month, number of days with no household work, number of days with reduced household work productivity, number of days with hired outside help, number of days missed of family/social/leisure activities in the last month.higher scores mean a worse outcome.
