Between 1997 and 2005, Wyeth paid medical communications firms to ghostwrite at least 40 articles that promoted hormone replacement for treatment of not just menopause symptoms, but also other conditions such as Parkinson's disease. These articles, many of them reviews of prior studies, played up the benefits of the hormone drugs while downplaying their risks. The communications firms also secured doctors to put their names on the studies as authors.
The articles were published in 18 different medical journals. Neither Wyeth nor the studies' purported authors informed the journals that the company had funded the studies and employed their writers.
