Preparing your article for submission

Before submitting a manuscript, please gather the following information

  • Author affiliations/Institutions
  • Departments
  • Phone and Fax Numbers
  • E-mail Addresses
  • Title. Your title must be under 90 characters (including spaces). Do not use abbreviations in the title.
  • Completed Author Conflict of Interest (COI) Forms. The electronic form is also available on ScholarOne Manuscripts web site, in the Author Centre (for more information about our Conflict of Interest policy, please see below).

Conflict of interest / Disclosures

The Journal requires that an International Committee of Medical Journal Editors (ICMJE) Conflict of Interest Form is completed by every author of the manuscript. We strongly suggest that the ICJME COI Form(s) is/are completed and submitted at the time of initial submission, however this will not be required until revision, or acceptance without revision.  If the editors request a revision from you, we will require that the forms be submitted to ScholarOne at the time you submit your revised manuscript.  If your paper is accepted for publication without revision, we will require that you submit the forms at that time.  Please note that we will not be able to move forward with your revised or accepted paper until a completed COI form for each author has been uploaded to the submission site. Additionally, each individual author should use the ICMJE disclosure form to generate the wording of their declarations. Authors should then add these declarations into their manuscript before submission. This paragraph must match all disclosures listed on the co-authors’ COI form(s).  Editors and peer reviewers must be able to refer to this information during the review process.

Information regarding actual or potential conflict of interests for each co-author must be listed.  The COI information must include actual or potential conflicts of interest for each co-author. If in doubt, disclose the relationship. Any financial interest, research grant, material support, or consulting fee associated with the contents of the manuscript must be declared.

These guidelines apply to each co-author and their immediate families. Potential conflicts of interest are not necessarily wrong, nor do they necessarily change the scientific validity of the research or opinion presented. Please note, however, that the Journal and readers should be aware of the potential conflict(s). Such conflicts will be published with the authors’ knowledge. If the editor considers any potential conflicts to compromise the validity of the content, the manuscript will not be accepted for publication.

The Publisher shall not after publication online correct any error or omission in author disclosure forms if not submitted correctly during the peer review process.

Cover Letter

A cover letter is required and must state that the manuscript has not been published elsewhere, except in abstract form, and is not under simultaneous consideration by another journal. The cover letter should also disclose if there are any potential conflicts of interest.


Titles for all manuscripts must not include abbreviations and must be under 90 characters including spaces.

Title page

Provide a word count for the abstract and the body of the manuscript in the first page.

Section Headings

Subtitles (such as Introduction, Discussion, etc.) should not be included in "Letter to the Editor," Brief Communications, and Neuroimaging Highlights manuscripts.


Acknowledgements, including recognition of financial support, should be included at the end of the text.

Statement of authorship

A statement of authorship that outlines the roles of each author should be provided. Please provide this using author initials only. 

The SI system (système international d'unités) should be used in reporting all laboratory data, even if originally reported in another system.

Reference style


References should be numbered in the order of their citation in the text. Those cited only in tables and legends for illustrations are numbered according to the sequence established by the first identification in the text of a particular table or illustration.

  • Titles of journals should be abbreviated according to the style used in Index Medicus.
  • List all authors when there are six or fewer; for seven or more, list only the first three and add "et al".
  • Provide the full title, year of publication, volume number and inclusive pagination for journal articles. Do not include issue numbers. Including DOI is strongly encouraged.
  • Unpublished articles should be cited as [in press]. Do not reference unpublished or "submitted" papers; these can be mentioned in the body of the text.

Cambridge University Press Copyright Requirements for Supplementary Material

At Cambridge University Press, all supplementary material is subject to the same copyright requirements as primary material.

I/we hereby assign to Cambridge University Press, full copyright in all formats and media in the said contribution, including in any supplementary materials that I/we may author in support of the online version.

English language editing services 

Authors, particularly those whose first language is not English, may wish to have their English-language manuscripts checked by a native speaker before submission. This step is optional, but may help to ensure that the academic content of the paper is fully understood by the Editor and any reviewers.  

In order to help prospective authors to prepare for submission and to reach their publication goals, Cambridge University Press offers a range of high-quality manuscript preparation services – including language editing – delivered in partnership with American Journal Experts. You can find out more on our Language Services page.

Please note that the use of any of these services is voluntary, and at the author's own expense. Use of these services does not guarantee that the manuscript will be accepted for publication, nor does it restrict the author to submitting to a Cambridge-published journal. 

Seeking permission for copyrighted material

If your article contains any material in which you do not own copyright, including figures, charts, tables, photographs or excerpts of text, you must obtain permission from the copyright holder to reuse that material. As the author it is your responsibility to obtain this permission and pay any related fees, and you will need to send us a copy of each permission statement at acceptance.

When do I need to request permission?

You need to request permission to reuse any material for which you are not the copyright holder. This can include anything created, published, owned, held or produced by a third party, but also other published material that you authored, as the original publisher may hold the copyright.

If you make minor changes to the original material, you still need to seek permission to use it. Cosmetic changes such as tinting, relabelling, or redrawing as is are not enough; material needs to be substantially modified to avoid needing permission to reproduce, and even then the original source still needs to be acknowledged.

Who do I send a permission request to?

Usually the publisher of the original work holds the copyright, unless explicitly stated otherwise. We recommend that you approach the original publisher first, and they will inform you if you need to contact the author.

How do I request permission?

Most publishers have forms on their websites that can be completed electronically, or use automated electronic permissions services like Rightslink® to grant permissions automatically online.

If no electronic form or service is available, you must send an email or letter to the copyright holder. A template permissions request is included below; note for emails no signature is required.

Dear <rightsholder>

<Article title>

I am writing/editing/contributing to an academic work under the provisional title above, to be published by Cambridge University Press in <title of journal>, in <month (if known) and year of publication>.

I request your permission to include the following material in this work:

Date of publication: <volume and issue if applicable>:
ISBN <ISSN if journal>:
Page no.(s):
Illustration no.(s):
Table no.(s):

Unless otherwise informed, permission will be assumed to grant the nonexclusive right to use the material in print and electronic editions of the work throughout the world, in all revised editions of the work and as part of a sample of the work made available online for promotional purposes only.

I further request permission for the material to be included in any reprint published under licence from Cambridge University Press.

The source of the material will be fully acknowledged in the usual way. Please indicate below if you have any special requirements: ..............................................................


Please indicate your agreement to this request by <way of reply to this email/signing and returning one copy of this letter>:. The duplicate is for your own records. By your countersignature, you warrant that you control these rights and are authorised to grant this permission.

If this is not the case, I would be grateful if you could let me know to whom I should apply.

Yours sincerely

<Signature lines>:

I/we hereby grant the permission detailed above.

Signed:............................. Date: ..................

When do I not need to request permission?
  • Creative Commons – where third party content is published under a Creative Commons licence (CC-BY / CC-BY-NC / CC-BY-NC-ND etc.), you may not need to request permission to reuse the content as long as you fully acknowledge the original source. Please check carefully the terms of the license before reusing material. More information about Creative Commons licenses can be found at
  • Content in the public domain – material that is not under copyright is considered to be in the public domain, and you do not need to request permission to use such material. This includes works for which the copyright has expired and has not since been renewed.
My article includes third party materials and will be published Gold Open Access. What type of permissions do I need to request?

If your article is to be published Gold Open Access, you will have to make sure all of the permissions requested from third party copyright owners includes the non-exclusive right to use the third party materials in the open access version of your article and under an equivalent creative commons licence.

If your article is transformed to a Gold OA publication post-submission, you will need to review the current permissions already in place and determine whether or not the rights originally granted cover the open access version of your article. If not, then you will need to request further permissions from the copyright holder.

How do I acknowledge permission in my paper?

Even if written permission is not required, you must fully acknowledge the original source of any material where you do not hold copyright in your article. The copyright holder will inform you if there is any specific wording required for this acknowledgement. For figures or tables from other sources, you should place this acknowledgement at the end of the caption.

What permissions information do I need to provide to my journal?

You will be asked to supply copies of any emails or letters granting permission to reuse material with your transfer of copyright or license to publish form.

Patient photographs

Please note that hospitals usually hold copyright for any photographs taken during the course of work done on their premises. Permission to use the photograph in your article also needs to be obtained from the patient in the photograph if the subject of the photograph can be recognised.

Material from the internet

Please be aware that even if a copyright notice is not displayed, content on websites is still protected by copyright and so permission to reuse material will need to be obtained from the copyright holder.


We require all corresponding authors to identify themselves using ORCID when submitting a manuscript to this journal. ORCID provides a unique identifier for researchers and, through integration with key research workflows such as manuscript submission and grant applications, provides the following benefits:

  • Discoverability: ORCID increases the discoverability of your publications, by enabling smarter publisher systems and by helping readers to reliably find work that you have authored.
  • Convenience: As more organisations use ORCID, providing your iD or using it to register for services will automatically link activities to your ORCID record, and will enable you to share this information with other systems and platforms you use, saving you re-keying information multiple times.
  • Keeping track: Your ORCID record is a neat place to store and (if you choose) share validated information about your research activities and affiliations.

See our ORCID FAQs for more information.

If you don’t already have an iD, you will need to create one if you decide to submit a manuscript to this journal. You can register for one directly from your user account on Editorial Manager, or alternatively via

If you already have an iD, please use this when submitting your manuscript, either by linking it to your Editorial Manager account, or by supplying it during submission.

ORCIDs can also be used if authors wish to communicate to readers up-to-date information about how they wish to be addressed or referred to (for example, they wish to include pronouns, additional titles, honorifics, name variations, etc.) alongside their published articles. We encourage authors to make use of the ORCID profile’s “Published Name” field for this purpose. This is entirely optional for authors who wish to communicate such information in connection with their article. Please note that this method is not currently recommended for author name changes: see Cambridge’s author name change policy if you want to change your name on an already published article. See our ORCID FAQs for more information.
