Mortality among patients with rheumatoid arthritis (RA) improved over time in a Canadian study.

Better treatment might be improving RA survival.
Population cohort study of all new patients with RA diagnosed in British Columbia between 1996 and 2006, matched with control patients from the general population by sex, age, and index year (24,914 in both groups), to compare 5-y all-cause and disease-specific mortality.
