Research Data Sharing Policy

IEJMS requires a data availability statement in every submission, and strongly encourages authors to make the data and code underlying their results openly available.

The data availability statement

Every manuscript must carry a data availability statement, even where no data are shared. It should say where the data underlying the reported results can be found, and under what conditions. Examples of acceptable statements:

• "The datasets generated and analysed in this study are available in the [repository name] repository, [persistent DOI link]."
• "All data supporting the findings are included in the article and its supplementary files."
• "The data are not publicly available because they contain information that could compromise participant privacy, but are available from the corresponding author on reasonable request."

Where to deposit

Deposit datasets in a recognised public repository — a subject-specific repository where one exists, otherwise a general one such as Zenodo, Figshare, Dryad or an institutional repository — and cite the dataset's DOI in the reference list.

Code

Where results depend on custom software, simulation or analysis scripts, the code should be shared under an open-source licence, with enough documentation for another researcher to reproduce the reported results. A version-tagged, archived release (for example a Zenodo DOI for a repository release) is preferred over a bare link to a live repository.

Legitimate reasons not to share

We recognise that data cannot always be public — participant privacy, third-party ownership, commercial confidentiality or legal restriction. In these cases authors must state the reason explicitly and describe how a reader could request access. "Data available on request" with no further detail is not sufficient.
