Twenty-four patients had died by 2006, 17 (42%) in the RA group and 7 (35%) in the non-RA group. Nine patients, all in the RA group (23%), had received 1 or more joint replacements. The mean HAQ score was 0.57 in the non-RA survivors (mean age 70 yrs), compared to 0.89 in the RA group (mean age 66 yrs) (p = 0.020, adjusted for age).
