Bias in
industry-sponsored
clinical trials


Evidence suggests that industry influence over
clinical trials has resulted in biased science.When
a drug is sold it is not sold alone but as part of a
package of science. The efficacy of the drug is
believed in because of the science that supports it.
However, through systematic bias created in
clinical trials inaccurate information is published and used as evidence when it comes to licensing decisions on the safety, efficacy and quality of drugs, and this in turn affects prescribing practices of doctors.
