JMPCC supports open and responsible data sharing. All research articles must include a Data Availability Statement.

Options for the statement

•     Data are openly available in [repository] at [DOI/URL].

•     Data are included in the article and supplementary files.

•     Data are available from the corresponding author on reasonable request, subject to approval by [the ethics committee / data custodian].

•     Data are from a registry or database (e.g., a national ICU registry or MIMIC) and can be obtained from [custodian] under its access conditions.

•     Data cannot be shared publicly because of participant confidentiality or legal restrictions; reasons are given.

Expectations

•     Share de-identified data where consent and ethics approval allow. Remove direct identifiers and consider indirect identifiers such as exact dates, rare conditions and hospital names.

•     Share study protocols, statistical analysis plans, analysis code and data dictionaries to support reproducibility. Recommended repositories include Zenodo, Figshare, Harvard Dataverse and OSF.

•     Data from clinical trials must be accompanied by a data sharing statement in line with ICMJE.

•     Data from hospitals and registries should be shared only with the agreement of the data custodian and in line with patient consent.

Editors may request raw data during review or after publication. Failure to provide data when concerns are raised may result in rejection, an expression of concern or retraction.
