The Editors have retracted this article after readers raised concerns around the methodology. A post-publication review highlighted concerns about the assumption of ‘0’ prevalence of e-cigarette use in 2010 which contradicts available data; this assumption is not fully supported by the sensitivity analyses performed by the authors. Therefore, the Editors have lost confidence in the results reported by the article. None of the authors agree to this retraction.
