1. The New England Journal of Medicine posts its peer-reviewed articles and editorials on its website. An opt-in poll was featured next to an editorial about the regulation of sugar-sweetened beverages. The poll asked, “Do you support government regulation of sugar-sweetened beverages?” Readers just needed to click on a response (yes or no) to become part of the sample. The poll stayed open for several weeks in October 2012. Of the 1290 votes cast, 864 were “yes” responses.
