DMJ believes that data sharing will always support other similar research. Sharing the full data sets underlying the results in your article brings many benefits. It enables reuse, and promotes collaborations with researchers in the same field and topic. Greater transparency increases trust in research results by allowing results to be independently verified which results in a more accurate review process. These benefits lead to a more reliable evidence base.

We strongly encourage that data generated by your research that supports your article be made available as soon as possible, wherever legally and ethically possible
We require data from clinical trials to be made available upon reasonable request (where there are confidentiality or sensitivity issues) The data could be shared through a controlled access repository.
The ICMJE recommendationsfor data availability provide further guidance on how to compose a rich statement.
These statements will be published under the header ‘Data Availability Statement’ within the footnotes section of the final published article.

•  Data are available in a public, open access repository:

Please state the repository name, the persistent URL, and any conditions of reuse (eg. license, embargo). All data that are publicly available and used in the writing of an article should be cited in the text and the reference list, whether they are data generated by the author(s) or by other researchers.

•  Data are available upon reasonable request

Please state what the data are (e.g. unidentified participant data), who the data are available from, their publishable contact details (e.g. a generic lab email address or an individual’s ORCID identifier – please ensure you have permission) and under what conditions reuse is permitted. Is there additional information available (e.g. protocols, statistical analysis plans)?

• Data may be obtained from a third party and are not publicly available

All data that are publicly available and used in the writing of an article should be cited in the text and the reference list – whether they are data generated by the author(s) or by other researchers.
Data citations should be in the Vancouver citation format (add link to how to cite like that), the Digital Object Identifier (DOI).

We consider any data generated by your research to be relevant and important for data sharing.
