As stated in the Uniform Requirements, credit for authorship requires substantial contributions to (a) the conception and design or analysis and interpretation of the data, and (b) the drafting of the article or critical revision for important intellectual content. Any change in authorship after submission must be approved in writing by all authors.
Conflict of interest
A conflict of interest may exist when an author (or the author's institution or employer) has financial or personal relationships that could inappropriately influence (or bias) the author's decisions, work, or manuscript. Corresponding author of an article is asked to let the Editor know potential conflict of interest possibly influencing their interpretation of data. Potential conflict of interest is applied even when the authors are confident that their judgments have not been influenced in the manuscript. Such conflicts may be financial supports or connections to pharmaceutical companies, political pressure from interest groups, or academic problems. The Editor will decide whether the information of the conflict should be included in the published paper. Before publishing such information, the Editor will consult with the corresponding author. In particular, all sources of funding for a research should be explicitly stated. CEO asks referees to let its Editor know of any conflict of interest before reviewing a particular manuscript.
For clinical trials, details of ethical committee approval and the type of informed consent should be stated. Patients' and volunteers' names, initials, and hospital numbers should not be used. We endorse the principles embodied in the Declaration of Helsinki and expect that all investigations involving human materials have been performed in accordance with these principles. For animal experiment, "the Guiding Principles in the Care and Use of Animals" approved by the American Physiological Society have to be observed.
No substantial part of the manuscript may have been or may be published elsewhere. This restriction does not apply to abstracts or press reports published in connection with scientific meetings. For advice on previous or simultaneous publication, contact the Editorial Office.
Upon acceptance of an article, authors will be asked to transfer copyright. This transfer will ensure the widest possible dissemination of information. A letter will be sent to the corresponding author confirming receipt of the manuscript. A form facilitating transfer of copyright will be provided. If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article. Requests may also be completed online: http://ceo.jatsxml.org/
Alteration in Proof
CEO provides the corresponding author with galley proofs for their correction. Corrections should be kept to minimum. The Editor retains the prerogative to question minor stylistic alterations and major alterations that might affect the scientific content of the paper. Fault found after the publication is a responsibility of the authors. We urge our contributors to proofread and their accepted manuscript very carefully. The corresponding author may be contacted by the Editorial Office, depending on the nature of correction in proof. If the proof is not returned to the Editorial Office within 48 hours, it may be necessary to reschedule the paper for a subsequent issue.
