This article has been retracted at the request of the Editor.
Post-publication, an investigation conducted on behalf of the journal by Elsevier's Research Integrity & Publishing Ethics team discovered suspicious changes in authorship between the original submission and the revised version of this paper. During revision, the authors Jianchun Fan, Junan Lu, Guanggui Zou, and Siwei Dai were added to the paper and one author was removed from the paper. These changes were made without explanation and without exceptional approval by the journal editor, which is contrary to the journal policy on changes to authorship. The Editor reached out to the authors for an explanation, but they failed to provide a satisfactory explanation to these changes. The Editor has determined that the authorship and the findings of the article cannot be relied upon, and has decided to retract the article.
The authors disagree with the retraction and dispute the grounds for it.
