Error in Financial Disclosure. In the Original Investigation by Hsia et al titled “Conjugated Equine Estrogens and Coronary Heart Disease: The Women's Health Initiative,” published in the February 13 issue of the ARCHIVES (2006;166:357-365), an error occurred in the financial disclosure. It should have appeared as follows: “Dr Langer received honoraria from Solvay Pharmaceuticals (Houston, Tex) and served as a consultant for Berlex (Montville, NJ), Monarch-King Pharmaceuticals (Bristol, Tenn), and Wyeth Pharmaceuticals (Collegeville, Pa). Dr Prentice received an honorarium from Wyeth Pharmaceuticals in 2004.” This correction was made previously to online versions of this article.
