Authorship and Contributorship
Author contributions
For transparency, we require corresponding authors to provide co-author contributions to the manuscript using the relevant CRediT roles. The CRediT taxonomy includes 14 different roles describing each contributor’s specific contribution to the scholarly output. The roles are: Conceptualization; Data curation; Formal analysis; Funding acquisition; Investigation; Methodology; Project administration; Resources; Software; Supervision; Validation; Visualization; Roles/Writing - original draft; and Writing - review & editing. Note that not all roles may apply to every manuscript, and authors may have contributed through multiple roles.
CRediT Roles
CRediT (Contributor Roles Taxonomy) was introduced with the intention of recognizing individual author contributions, reducing authorship disputes and facilitating collaboration. The idea came about following a 2012 collaborative workshop led by Harvard University and the Wellcome Trust, with input from researchers, the International Committee of Medical Journal Editors (ICMJE) and publishers, including Elsevier, represented by Cell Press.
CRediT offers authors the opportunity to share an accurate and detailed description of their diverse contributions to the published work.
-
The corresponding author is responsible for ensuring that the descriptions are accurate and agreed by all authors
-
The role(s) of all authors should be listed, using the relevant above categories
-
Authors may have contributed in multiple roles
-
CRediT in no way changes the journal’s criteria to qualify for authorship
CRediT statements should be provided during the submission process and will appear above the acknowledgment section of the published paper as shown further below.
- Conceptualization – Ideas; formulation or evolution of overarching research goals and aims.
- Data curation – Management activities to annotate (produce metadata), scrub data and maintain research data (including software code, where it is necessary for interpreting the data itself) for initial use and later re-use.
- Formal analysis – Application of statistical, mathematical, computational, or other formal techniques to analyze or synthesize study data.
- Funding acquisition - Acquisition of the financial support for the project leading to this publication.
- Investigation – Conducting a research and investigation process, specifically performing the experiments, or data/evidence collection.
- Methodology – Development or design of methodology; creation of models.
- Project administration – Management and coordination responsibility for the research activity planning and execution.
- Resources – Provision of study materials, reagents, materials, patients, laboratory samples, animals, instrumentation, computing resources, or other analysis tools.
- Software – Programming, software development; designing computer programs; implementation of the computer code and supporting algorithms; testing of existing code components.
- Supervision – Oversight and leadership responsibility for the research activity planning and execution, including mentorship external to the core team.
- Validation – Verification, whether as a part of the activity or separate, of the overall replication/reproducibility of results/experiments and other research outputs.
- Visualization – Preparation, creation and/or presentation of the published work, specifically visualization/data presentation.
- Writing – original draft – Preparation, creation and/or presentation of the published work, specifically writing the initial draft (including substantive translation).
- Writing – review & editing – Preparation, creation and/or presentation of the published work by those from the original research group, specifically critical review, commentary or revision – including pre- or post-publication stages.

Changes to authorship
Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.
Only in exceptional circumstances will the Editor consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editor considers the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editor will result in a corrigendum.
