3.12 Do authors reveal funding sources?
Wilkes and Kravitz184 surveyed 221 North American medical journal editors and found that only 26% required authors to reveal their funding sources. Sacristan et al.185 report that in a large number of pharmacoeconomic studies funding sources are not specified. Moynihan et al.186 found that ties between researchers and industry were often omitted from media reports about drugs.
CONCLUSION: Funding from pharmaceutical companies is often not disclosed.
