Abstract

The Competing Interests statement for this article [1] states that one of the authors received grant funding from the Smoking Research Foundation, which according to [2] has received financial support from the tobacco industry. It is unclear whether Smoking Research Foundation grant funding contributed to the author's salary or research costs during the period when the study reported in [1] was conducted. The foundation is not listed as a primary funder for this study in the article's Funding Statement. In light of this issue the PLOS ONE article [1] may not comply with the journal's policy on Funding from Tobacco Companies [3] which was implemented in 2010. Therefore, the PLOS ONE Editors issue this Expression of Concern. We regret that this concern was not identified and addressed prior to the article's [1] publication.
