It recently came to our attention that the Academic Editor Bharat Aggarwal had collaborated and co-authored different publications with the senior author of the article over the four years that preceded this submission.

In line with the PLOS ONE competing interests policy (, we consider this as a potential conflict of interest. We have therefore asked the Academic Editor Subhash Gautam to carefully evaluate the peer review process of this article. Dr Gautam has confirmed that he is satisfied that the peer review process and the decision for publication are adequate.
