Medical Journal Cites Misleading Drug Research

Nov 10, 199 By DENISE GRADY

Reports of research on drugs tend to exaggerate the drugs' benefits, making them sound better than they really are, according to an article and editorial being published
Wednesday in The Journal of the American Medical Association.

The exaggeration occurs for several reasons: positive results tend to be published more often than negative ones, researchers sometimes publish the same study more than
once and some poorly designed studies slip through the safety net of journal editors and expert reviewers who should screen them out.
