When thousands of psychiatrists attend their field's largest annual meeting each year, the presentations they hear about research into drug treatments report overwhelmingly on positive results.

That's the finding of a new study published in the Journal of Clinical Psychopharmacology by two young psychiatrists from the University of Michigan and Yale University, who analyzed the presentations given at two recent meetings of the American Psychiatric Association.

Of 278 studies presented at the 2009 and 2010 APA meetings that compared at least two medicines against each other for any psychiatric illness, they found that 195 had been supported by industry, and 83 funded by other means. The authors then evaluated the studies without knowing which kind of support each one had.

Of the industry-supported studies, 97.4 percent reported results that were positive toward the medicine that the study was designed to test, and 2.6 percent reported mixed results. No industry-sponsored studies with negative results were found.
