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. ==== Refs Reference 1.
