Elsevier is doing its own investigation into whether an "Editor's Choice" article appearing in the May 2003 issue of the American Journal of Obstetrics and Gynecology was "improperly ghostwritten by a drug company promoting the product," the New York Times reports. This inquiry follows on the heels of Senator Charles Grassley (R-Iowa) saying that Wyeth commissioned the article and it was written by DesignWrite, and only after that was a physician, John Eden of the University of New South Wales, found to author the article.
The article under investigation addressed the Women's Health Initiative, which ended early when women taking Wyeth's Prempro were found to have a higher risk of developing breast cancer and it said "any association of progesterone with breast cancer risk remains controversial."
