The biomedical enterprise depends on good science for its foundation, and good science requires transparency of methods and integrity of purpose. Industry plays a major role in supporting biomedical science, supplying nearly half of the estimated $94 billion devoted to such investigations in 2004.1 While industry support for clinical research is essential, commercial bias may be introduced in a variety of ways. These range from trial design to nonpublication of negative findings and aggressive marketing.2 These distortions have a substantial negative impact on scientific knowledge and clinical care.
