Most pharmaceutical companies have sworn off ghostwriting, the practice of writing research" papers for doctors and then paying them to add their names as authors even when they had little involvement or the results were trivial. Merck (MRK), Forest Labs (FRX), and GlaxoSmithKline (GSK) have all been caught doing it. But what happens to the articles that have been disavowed by companies or discredited by lawyers? Not much, it turns out. They sit inside prestigious online archives of academic material, unretracted, where they look just like real studies with robust results. Ghostwriting doesn't look good in lawsuits, either. Pfizer (PFE) must now pay $9.5 million to a woman who claimed menopause drug Prempro gave her breast cancer; Wyeth - the company that made the drug and was later acquired by Pfizer - commissioned ghostwritten articles about the drug. So it's interesting to note that many of those pay-for-play articles are still sitting in scholarly archives such as PubMed, notching up bibliography references and footnotes, even though they shouldn't be.
