In the editorial by Hochman and Shah, “What Price Pain Relief?,” which appeared in the June 27, 2006, issue (Circulation. 2006;113:2868–2870), a reference was omitted. This caused a shift of several citations. The sentence, “Despite time-tradeoff analyses that often reveal a wide range of patient preferences for quality versus quantity of life, the need for safe and effective treatment options is clear” should cite reference 16. The sentence, “An analysis of data from the Nurses Health Study found a dose-response association between acetaminophen use and cardiovascular risk,” which originally cited reference 16, should cite the following reference: Cheng Y, Wang M, Yu Y, Lawson J, Funk CD, FitzGerald GA. Cyclooxygenases, microsomal prostaglandin E synthase-1, and cardiovascular function. J Clin Invest. 2006;116:1391–1399. This was added as reference 17 and subsequent references have been renumbered in the revised PDF available with this article (http://circ.ahajournals.org/reprint/113/25/2868).
The authors apologize for the misattribution.
