The editor has retracted this article [1]. In the accompanying trial registry [2] the authors stated that they conducted three separate arms of this clinical trial. The article only reports the results of two of the arms. The data and the results of this article are therefore unreliable. Additionally, there is considerable overlap with a previously published article by the same authors [3].
