Erratum

In the article by Stringer et al in the November 2008 issue of Arthritis & Rheumatism (pages 3585–3592), there were several errors in Table 1. The number of Asian patients should be 12 (not 14), the data on clinical characteristics at first visit refer to the percentage (not the number) of patients in the cohort, and the percentage with skin ulcers should be 12% (not 10%).

We regret the errors.
