The Netherlands Journal of Critical Care (Neth. J. Crit. Care) supports transparency, research integrity, and reproducibility in scientific publishing. We believe that appropriate research data sharing and citation through standard reference lists provide readers and researchers with a reliable and accessible way to locate supporting data and reproduce published research where ethically and technically possible.

1. Research Data Transparency

Authors are encouraged to provide sufficient information about the data, methods, materials, and analytical procedures used in their research to allow qualified researchers to understand, evaluate, and, where appropriate, reproduce the reported findings.

2. Data Availability Statement

Authors are encouraged to include a clear Data Availability Statement indicating how the data supporting the findings can be accessed.

Where applicable, authors should state whether the data are:

• Publicly available through a recognized repository.
• Available from the corresponding author upon reasonable request.
• Available subject to ethical, privacy, or legal restrictions.
• Not available for sharing because of legitimate confidentiality or regulatory limitations.

3. Data Citation

The journal encourages authors to cite research datasets and other underlying research resources using standard scholarly citation practices.

Where a dataset is publicly available, authors should provide sufficient bibliographic information and a persistent identifier, such as a DOI, accession number, or stable repository link, where available.

Data citations should be included in the reference list where appropriate so that readers can easily identify and access the underlying data.

4. Reproducibility

Authors should provide sufficient methodological detail to enable readers and qualified researchers to understand how the study was conducted and, where feasible, reproduce the reported analyses and findings.

Where appropriate, authors are encouraged to provide access to:

• Research datasets
• Study protocols
• Statistical analysis procedures
• Software or code
• Research materials
• Supplementary files
• Other resources necessary to support reproducibility

5. Human Participant Data

Data involving human participants must be handled in accordance with informed-consent requirements, ethical approval, privacy protections, and applicable laws.

Personally identifiable or confidential information must not be publicly shared unless appropriate authorization and consent have been obtained.

Where data cannot be openly shared, authors should explain the relevant restrictions and, where feasible, provide a controlled-access mechanism for qualified researchers.

6. Data Integrity

Authors are responsible for ensuring that research data are accurate, appropriately documented, and consistent with the results reported in the manuscript.

Fabrication, falsification, inappropriate manipulation, selective reporting, or misrepresentation of research data constitutes a serious breach of research and publication ethics.

7. Access to Supporting Data

The editorial team may request access to relevant supporting data, documentation, or methodological information during peer review or after publication where necessary to investigate questions concerning the accuracy, integrity, or reproducibility of the research.

Authors should retain appropriate research records for a reasonable period in accordance with applicable institutional, funder, ethical, and legal requirements.

8. Corrections and Post-Publication Concerns

If concerns arise after publication regarding the data, analyses, or reproducibility of an article, the journal may request clarification or supporting information from the authors.

Where appropriate, the journal may publish a correction, expression of concern, or retraction in accordance with its publication-ethics policies.

9. Commitment to Reproducible Research

The Netherlands Journal of Critical Care encourages responsible data sharing, transparent reporting, standardized data citation, and accessible supporting materials to strengthen the reliability and reproducibility of published research.

The journal recognizes that data sharing may not always be possible because of ethical, legal, privacy, confidentiality, or intellectual-property considerations. In such cases, authors should provide a clear explanation of the applicable restrictions while making reasonable efforts to support research transparency.
