Authorships

Authorship should meet the following 3 points at the same time:

• having made substantial contributions to the conception, design, acquisition and analysis of data;
• having made intellectual contribution to writing the manuscript or revising it;
• final approval of the version to be published.

All authors must read and approve the final version of the manuscript. All the authors have the right to explain the questions raised, and agree the author rank before publishing.

Changes to Authorship

The Editorial Office considers the authorship list is definitive by the time the original submission is received.

Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript is accepted for publication. The corresponding author should provide the reasons for the change in the authorship list and the proof of written confirmation from all authors (including the existing authors, author(s) to be added and/or removed) agreeing with such change, to the Editorial Office.

The requests for authorship changes need to be approved by the Editorial Office before any changes can be made.
