In the article by Antoni et al published in the April 2005 issue of Arthritis & Rheumatism (pp. 1227–1236), there was an error in the first footnote to Table 2. The sentence published as “Except where indicated otherwise, all other values are the mean ± SD percent improvement (a negative value indicates worsening)” should have read “Except where indicated otherwise, all other values are the mean ± SEM percent improvement (a negative value indicates worsening).”
