to draft research reports before handing them over to the doctors whose
names eventually appear on the publication. But the company disputed
the article's conclusion that the authors do little of the actual
research or analysis.
The final work is the product of the doctor

James C. Fitzpatrick.
And at least one of the doctors whose published research was questioned in Wednesday's article, Dr. Steven H. Ferris, a New York Universitypsychiatry
professor, said the notion that the article bearing his name was
ghostwritten was "simply false." He said it was "egregious" that Dr.
Ross and his colleagues had done no research besides mining the Merck
documents and reading the published journal articles.
In an editorial, JAMA said the analysis showed that Merck had apparently manipulated dozens of publications to promote Vioxx.
is clear that at least some of the authors played little direct roles
in the study or review, yet still allowed themselves to be named as
authors," the editorial said.
The editorial called upon medical
journal editors to require each author to report his or her specific
contributions to articles. "Journal editors also bear some of the
responsibility for enabling companies to manipulate publications," the

serious as allowing someone to have a review article written by a
for-profit company and solicited and paid for by a for-profit company

the role of pharmaceutical companies in influencing medical journal

most comprehensive look at the practice yet, according to one of the

plaintiffs. Those documents were available to Dr. Egilman and Dr. Ross
because they had served as consultants to plaintiffs' lawyers in some
of those suits.
Combing through the documents, Dr. Ross and his
colleagues unearthed internal Merck e-mail messages and documents about
96 journal publications, which included review articles and reports of
clinical studies. While the Ross team said it was not necessarily
raising questions about all 96 articles, it said that in many cases
there was scant evidence that the recruited authors made substantive

third author, also not named on the initial draft, was Dr. Louis Kirby,
currently the medical director for the company Provista Life Sciences.
In an e-mail message on Tuesday, Dr. Kirby said that as a clinical
investigator for the study he had enrolled more patients, 109, than any
of the other researchers. He also said he made revisions to the final
"The fact that the draft was written by a Merck
employee for later discussion by all the authors does not in and of
itself constitute ghostwriting," Dr. Kirby's e-mail message said.
The current editor of the journal Neuropsychopharmacology, Dr. James H. Meador-Woodruff, the chairman of psychiatry at the University of Alabama,
Birmingham, said he was not the editor in 2005 but planned to
investigate the accusations. "Currently, we have in place prohibitions
against this," Dr. Meador-Woodruff said.
