CRediT (Contribution Roles Taxonomy)

Journals mandating CRediT (Contributor Roles Taxonomy) will enable authors to provide information on submission, allowing for detailed information about individual contributions to the work. If not provided on submission, this information can be provided at subsequent revision stages, facilitated by the Editorial Office. The submitting author is responsible for ensuring that contributions of all authors are correct. It is expected that all authors will have reviewed, discussed and agreed to their individual contributions as shared by the submitting author. The authors’ contribution statement will be published with the final article and should accurately reflect contributions to the work.


CRediT Classification:

    • 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 reuse.

    • 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.
