Table 2 Change in response to treatment in the Disease Activity Score 28 (DAS28) and Health Assessment Questionnaire Disability Index (HAQ) in patients with active rheumatoid arthritis

	Duration of rheumatoid arthritis (years)
	<10	10–19.9	⩾20
Mean baseline DAS28	6.1	6.0	6.1
Mean change in DAS28	−1.2	−0.8	−1.0

Mean baseline HAQ	1.31	1.48	1.40
Mean change in HAQ	−0.36	−0.22	−0.13

Responses were measured after either 1 month (for patients treated with corticosteroids) or 4 months (all others). The DAS28 can range from 0 to 10, with scores above 5.1 considered to represent highly active rheumatoid arthritis. HAQ scores can range from 0 to 3.0, with higher scores indicating more functional limitations.
