The Editor-in-Chief has retracted this article  due to a number of concerns that have come to light after publication. The clinical trial registry  for this study states that the study start date is 12 February 2012. However, documentation regarding the ethical approval provided by the corresponding author shows that the authors applied for ethics approval on 18 February 2012, and that the ethics committee approved the study on 17 September 2012. Additionally, the time stamp on Fig. 4a is 11 September 2012 and on Fig. 4b it’s 27 February 2010, which suggests the research was conducted before ethics approval was obtained. The Editor-in-Chief therefore no longer has confidence in the reliability of the data reported in the article.
