The Editor-in-Chief has retracted this article. Concerns have been raised about overlap with another published study [1]. The authors have not responded to a request from the Editor-in-Chief for an explanation of this overlap. The Editor-in-Chief therefore no longer has confidence in the results and conclusions presented. None of the authors has responded to correspondence from the Publisher about this retraction.
