REPORTING STANDARDS Authors reporting results of original research should present an accurate account of the work performed as well as an objective discussion of its significance. Underlying data should be represented accurately in the manuscript. A paper should contain sufficient detail and references to permit others to replicate the work. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Originality and plagiarism The authors should ensure that they have written entirely original works, and if the authors have used the work and/or words of others that this has been appropriately cited or quoted.
MULTIPLE, REDUNDANT, OR CONCURRENT PUBLICATION An author should not in general publish manuscripts describing essentially the same research in more than one journal or primary publication. Parallel submission of the same manuscript to more than one journal constitutes unethical publishing behavior and is unacceptable.
ACKNOWLEDGEMENT OF SOURCES Proper acknowledgment of the work of others must always be given. Authors should also cite publications that have been influential in determining the nature of the reported work.
AUTHORSHIP OF A MANUSCRIPT Authorship should be limited to those who have made a significant contribution to the conception, design, execution, or interpretation of the reported study. All those who have made significant contributions should be listed as coauthors. Where there are others who have participated in certain substantive aspects of the research project, they should be named in an Acknowledgement section. The corresponding author should ensure that all appropriate coauthors (according to the above definition) and no inappropriate co-authors are included in the author list of the manuscript, and that all co-authors have seen and approved the final version of the paper and have agreed to its submission for publication. All co-authors must be clearly indicated at the time of manuscript submission. Requests to add co-authors after a manuscript has been accepted will require approval of the editor.
DISCLOSURE AND CONFLICTS OF INTEREST All authors should disclose in their manuscript any financial or other substantive conflict of interest that might be construed to influence the results or their interpretation in the manuscript. All sources of financial support for the project should be disclosed.
FUNDAMENTAL ERRORS IN PUBLISHED WORKS When an author discovers a significant error or inaccuracy in his/her own published work, it is the author’s obligation to promptly notify the journal’s editor or publisher and cooperate with them to either retract the paper or to publish an appropriate correction statement or erratum.
