Cash interests taint drug advice | Nature

Only one author declared a conflict of interest, but further checks by the CSPI revealed that four other authors had failed to disclose research funding from relevant drug companies. The problem could be even worse in guidelines that don't contain conflict-of-interest declarations, warns Merrill Goozner, director of the CSPI's Integrity in Science project. “It is usually the journals and supplements that rely heavily on industry advertising that are least likely to have good disclosure policies.”
