The Editor has retracted this article [1] because upon investigation the authors have been unable to provide documents confirming that ethics approval was obtained prior to study commencement. Further, numerous discrepancies have been found between the trial registration and the published article regarding recruitment dates, number of participants being recruited and age of participants. Finally, the authors have informed the journal that they included control data collected as part of a different trial. As such, the editor is no longer confident in the reliability of the data underlying the conclusions.

Author Dan Lu has stated on behalf of all co-authors that they agree to this retraction.
