Data Archiving Permissions
IJAN supports responsible data sharing to strengthen reproducibility and advance perioperative medicine. Authors are encouraged to deposit datasets, protocols, and code in trusted repositories when feasible.
Data Availability
Every article must include a data availability statement.
- Repository links preferred
- Privacy protections respected
- Embargoes supported when needed
Why Data Archiving Matters
Open data supports clinical validation, secondary analysis, and evidence based care. In anesthesia, reproducible datasets help optimize medication dosing, monitor safety outcomes, and inform perioperative guidelines.
Improved Reproducibility
Archiving data allows researchers to verify findings, compare results across populations, and build on prior work.
Funder Compliance
Many funders require data sharing plans. IJAN supports compliance through clear data availability statements.
Clinical Impact
Shared datasets accelerate translation of anesthetic research into practice and promote safer care pathways.
Long Term Preservation
Repositories provide stable access and persistent identifiers that keep data available beyond the publication date.
Where To Deposit Data
IJAN recommends trusted general or domain specific repositories that provide persistent identifiers. Examples include institutional repositories, data journals, and public data platforms that meet ethical requirements.
Institutional Repositories
University and hospital repositories provide secure long term storage aligned with local policies.
Discipline Specific Repositories
Use clinical or pharmacology repositories when available to ensure specialist accessibility.
General Repositories
General repositories offer open access storage for datasets, code, and protocols with DOI assignment.
Include repository name, persistent identifier, and access details within the data availability statement.
When Data Cannot Be Shared
IJAN recognizes legitimate restrictions, especially for patient privacy, sensitive clinical data, or regulatory limitations. When full sharing is not possible, provide a clear explanation and state how qualified researchers can request access.
Privacy And Confidentiality
Remove identifying information and follow HIPAA, GDPR, or local regulations for patient protection.
Controlled Access
Use repositories that allow restricted access for qualified researchers and track data use agreements.
Embargo Periods
Embargoes may be allowed to support ongoing analysis or pending patents. Provide an expected release date.
Third Party Data
When data are owned by third parties, explain permission limitations and cite the data source appropriately.
Authors must ensure that shared data do not compromise patient safety or violate institutional review board requirements.
Required In Every Article
Every IJAN submission must include a data availability statement. Use one of the following formats and tailor it to your dataset:
- Data are available in a public repository with a persistent link.
- Data are available from the corresponding author upon reasonable request.
- Data are restricted due to privacy or regulatory requirements.
- No new data were generated during the study.
Include accession numbers, repository links, and any access conditions in the statement.
Questions About Data Sharing?
Contact the editorial office at [email protected] for guidance on data archiving, permissions, or repository selection.
Preparing Data For Sharing
Before sharing data, remove identifiable patient information and document any de identification methods used. Provide data dictionaries that define variables, units, and coding decisions. When possible, share analytic code to improve transparency and reproducibility.
Use open, non proprietary formats when possible to ensure long term accessibility. If proprietary formats are required, include instructions for access.
Protect Patients While Sharing Data
When sharing clinical datasets, remove direct identifiers and evaluate indirect identifiers that could lead to re identification. Follow institutional policies for data governance and document the de identification process in your data availability statement.
If data contain sensitive information, consider controlled access repositories that require data use agreements. These controls can protect patient privacy while still enabling legitimate research reuse.
Clarity For Readers
Describe whether data are immediately available or subject to access conditions. Provide contact details for data requests and specify any required agreements.
Supporting Materials
When possible, share analysis scripts or code to improve reproducibility. If code cannot be shared, explain the restriction in the data availability statement.
Cite Shared Data
When data are archived, cite the dataset in the reference list using the repository DOI or accession number. Data citation supports reuse and credit.
Encouraging Reuse
Clear documentation improves data reuse and supports reliable secondary analysis.
Reasonable Access
When data cannot be public, provide a process for qualified researchers to request access.
