Abstract

Studies of drug treatments are more likely to report favourable outcomes when they are funded by the pharmaceutical industry. We compared drug trials reported in three major psychiatric journals to investigate these influences. Independent studies were more likely to report negative findings than industry-funded studies. However, the involvement of a drug company employee had a much greater effect on study outcome than financial sponsorship alone.
