(All estimates are unstandardized indirect effects and 95% bias-corrected bootstrap confidence intervals.) Conclusions: Concern over pharmaceutical companies hiding their affiliations and strategically controlling user-generated comments is well founded; these practices can greatly affect not only how viewers evaluate drug information online, but also how likely they are to propagate the information throughout their online and offline social networks.
