Authorship Criteria
Who Is an Author?

Xia & He has adopted the guidelines of the International Committee of Medical Journal Editors for the definition of authorship applied to submissions. All those designated as authors should meet all four criteria for authorship, and all who meet the four criteria should be identified as authors.

· Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
· Drafting the work or revising it critically for important intellectual content; AND
· Final approval of the version to be published; AND
· Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

In addition to being accountable for the parts of the work he or she has done, an author should be able to identify which co-authors are responsible for specific other parts of the work. In addition, authors should have confidence in the integrity of the contributions of their co-authors.

All persons listed as authors on the first submission of the manuscript to a journal should remain as authors throughout subsequent revisions; otherwise, an explanation and signed statement of agreement for the requested change from all listed authors and from the author to be removed or added should be provided to the journal.

A corresponding author should be identified, who takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process, and typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and gathering conflict of interest forms and statements, are properly completed, although these duties may be delegated to one or more coauthors. The corresponding author should be available throughout the submission and peer review process to respond to editorial queries in a timely way, and should be available after publication to respond to critiques of the work and cooperate with any requests from the journal for data or additional information should questions about the paper arise after publication.

Non-Author Contributors

All persons who contributed to the study or manuscript but who do not fulfill all of the criteria of authorship should be acknowledged (under “Acknowledgments” in the manuscript), subsequent to obtaining their written permission for acknowledgement. This includes persons responsible for funding, general supervision of a research group or general administrative support, writing assistance, technical editing, language editing, proofreading, advising, supplying materials, critical review, and so forth.
