New authors

The Cochrane Metabolic and Endocrine Disorders (CMED) group welcomes enquiries from prospective review authors. If you wish to author a review, we recommend that you browse through the existing CMED group projects (CMED titles, protocols, reviews and review updates) to identify a topic that has not yet been reviewed. Please note: Make sure that your proposal falls within our group's scope and that it has not already been covered in an existing Cochrane review!

Some important instructions for submitting a title proposal

We receive a great number of title requets. Our resources are limited and we cannot accept all title applications. We have to make difficult decisions as to which titles are priorities. One way we prioritize titles is to invite review authors to initially submit PICOS, this allows the editors to decide which title is of interest to them.  We offer no guarantees that any PICOS will be chosen. It is up to the CMED group's editors as to which are of interest to them.

We now ask all review authors to submit the following key information: title, PICOS (population, intervention, control, outcomes, types of studies) and clinical question.

  • Due to the CMED group's limited resources prioritisation policies apply: title proposals investigating questions of considerable public-health relevance and providing substantial evidence on patient-important outcome measures receive priority. We require at least one author experienced in writing Cochrane systematic reviews to be an active member of the review authors team. Integration of a statistician with experience in meta-analysis is strongly recommended.
  • At least two review authors are needed to prepare a Cochrane review.
  • If review authors want to include non-experimental or uncontrolled studies in their review they should contact the CMED group before or at title registration stage. The CMED group will ask review authors to prove that they are able to critically appraise observational studies such as establishing complete GRADE evidence profile tables for all evaluated main outcomes.
  • Every review author registering a title with the CMED group has to continuously check on emails from an alert service established by the CMED group's Information Specialist in order to stay informed about the newest published trials regarding his project.
  • The support of the editorial team in producing your review is conditional upon your agreement to publish the protocol, finished review and subsequent updates in the Cochrane Library. After registering of your title you agree to publish your protocol and review in the Cochrane Libray before publishing elsewhere (concurrent publication in other journals may be allowed in certain circumstances with prior permission of the Editorial Team).

Types of Cochrane Reviews

  • Intervention review
  • Diagnostic test accuracy (DTA) review
  • Methodology review
  • Overview of  Cochrane reviews

At present, the CMED group is accepting title registration forms for intervention reviews, DTA reviews and overviews of Cochrane reviews. Title registrations for DTA reviews will be handled on a case-by-case basis due to priority policies and limited CMED group's resources. Methodology reviews are prepared by the Cochrane methodology review group.

How to register a title

To register an intervention review title, complete the title registration form (click here to download Word file) and email it to the Assistant Managing Editor, Gudrun Paletta (paletta@med.uni-duesseldorf.de).

To register a DTA review title or a Cochrane overview title first contact the Assistant Managing Editor, Gudrun Paletta (paletta@med.uni-duesseldorf.de).

Contact person

Contact details should be provided for the person to whom correspondence about the review should be addressed, and who has agreed to take responsibility for maintaining and developing the review. Most usually, this person would:

  • Be responsible for developing and organizing the review team.
  • Communicate with the editorial office.
  • Ensure that the review is prepared within agreed timescales.
  • Submit the review for editorial approval via Review Manager and Archie.
  • Communicate feedback to co-authors.
  • Ensure that the updates are prepared.

The contact person need not be listed as a review author, and the choice of contact person will not affect the citation for the review.

Maximum number of simultaneously registered titles

To ensure quality and continuity new review authors should register a maximum of two CMED group review titles. Review authors should also inform the CMED group about ongoing projects with other Cochrane review groups.

What happens next?

You will receive an email confirmation that the CMED group has received your title registration form. The CMED group's editors will review the application and indicate whether the review will be registered. We will also assess the capacity of the review author team to carry out the Cochrane review. Completing and submitting your title registration form is not a guarantee that your review will be accepted.

Within usually two weeks, the Assistant Managing Editor will email you to let you know if the title has been accepted or declined. If accepted, the Assistant Managing Editor will follow up with information on how to get started on the protocol and to agree timelines.
