The Editor-in-Chief has retracted this article. After publication concerns arose regarding the authorship of this article. Contrary to the data availability statement, the authors have not provided the underlying data on the editor's request. Additionally, the authors have not been able to provide documentation that ethical approval was obtained prior to commencing this study. The ethics approval number as stated in this article appears to be identical to an ethics approval number in a previously published article by some of the same authors [1]. The Editor-in-Chief therefore no longer has confidence in the reliability of the data reported in the article. The authors did not explicitly state whether they agree to this retraction.
