All the individuals listed as authors in the manuscript must be based on the requirements stated by the International Committee of Medica Journal Editors (ICMJE)

The following conditions must be met for all the listed authors:

  • -Substantially contributing to the conception and design, acquisition of data, or analysis and interpretation of data, and
  • -Drafting the work or revising it critically for important intellectual content, and
  • -Final approval of the version to be published, and
  • -Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Group Authorship
We suggest following ICMJE recommendations as follows:

When a large, multicenter group has conducted the work, the group should identify the individuals who accept direct responsibility for the manuscript. These individuals should fully meet the criteria for authorship/contributorship defined above, and editors will ask these individuals to complete journal-specific author and conflict-of-interest disclosure forms. Acquisition of funding, collection of data, or general supervision of the research group alone does not constitute authorship.

When submitting a manuscript authored by a group, the corresponding author should clearly indicate the preferred citation in the manuscript title page and identify all individual authors as well as the group name. Journals generally list other members of the group in the Acknowledgments.


Author Contributions
UOJM has adopted the CRediT Taxonomy to describe each author’s individual contributions to the submitted work. The submitting author is solely responsible for providing this information as discussed and agreed with the co-authors. Authors should include a statement reflecting the contribution of the authors to the work. CRediT statement should be constructed using the following terms:

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.

An example of a CRediT author statement:

Omar Dewidar: Conception, Methodology, Writing – Original Draft Preparation
Zacharie-Saint Georges: Data curation, Software Faizan Khan: Supervision, Writing – Review & Editing

Contributors that do not meet the eligibility criteria for authorship should be acknowledged for their contributions in the acknowledgements statement.

Corresponding Author
The individual that speaks on behalf of the authors is considered the corresponding author.

The corresponding author is responsible for:

  • -Ensuring that the submission meets all the policy requirements set by UOJM
  • -Ensuring that all the authors approve the final version of the manuscript
  • -Ensuring that submitted version of the manuscript is shared with all the authors
  • -Informing all the coauthors of updates regarding the manuscript such as peer review comments and missing documents

Changes in Authorship
UOJM will follow COPE guidelines for changes in authorship. Any changes to authorship such as additions, deletions or changes in order will require agreement of all authors. All requests must be accompanied with an explanation of the change. If UOJM deems the change to be appropriate, the corresponding author must provide a document consenting the change from all authors.
