Drug companies fund a growing number of the studies in leading psychiatric journals, and drugs fare much better in these company-funded studies than in trials done independently or by competitors, researchers reported Wednesday. About 57% of published studies were paid for by drug companies in 2002, compared with 25% in 1992, says psychiatrist Igor Galynker of Beth Israel Medical Center in New York City. His team looked at clinical research in four influential journals: American Journal of Psychiatry, Archives of General Psychiatry, Journal of Clinical Psychiatry and Journal of Clinical Psychopharmacology. In the report, released at the American Psychiatric Association meeting in Toronto, reviewers did not know who paid for the studies they evaluated, Galynker says. There were favorable outcomes for a medication in about: eight out of 10 studies paid for by the company that makes the drug; five out of 10 studies done with no industry support; three out of 10 studies done by competitors of the firm making the drug. As drug companies increasingly fund research that yields favorable outcomes for their drugs, there may be a built-in bias because journals are reluctant to publish studies with negative or inconclusive findings.
