Preserve Chronic Disease Evidence for Long Term Use
JCD supports responsible data archiving so findings remain accessible, verifiable, and reusable. Our permissions policy balances transparency with patient privacy and regulatory compliance.
Archiving Supports Transparency
Authors are encouraged to archive data, protocols, and analytic code when feasible. This strengthens trust in chronic disease research and helps clinicians and policymakers evaluate evidence for practice change.
Well documented archives allow future researchers to validate outcomes, compare interventions, and build evidence for guideline development. JCD supports archiving that advances science without compromising participant privacy.
What You Can Archive
Authors may deposit de identified data sets, analysis scripts, statistical code, and study protocols in appropriate repositories. Supplementary materials that clarify methods are also welcome.
What Requires Caution
Patient level data that could reveal identity must be protected or anonymized. Sensitive information should only be shared when ethical approvals and legal frameworks allow it.
Which Article Versions Can Be Shared
JCD supports archiving to improve access while maintaining the integrity of the published record.
Accepted Manuscripts
Authors may archive accepted manuscripts in institutional repositories or personal websites with clear citation to the final published article. This helps expand access while preserving reference accuracy.
Published Version
The final published version is openly accessible on the JCD site. Authors may share links to the published article to drive discovery and ensure readers access the authoritative version.
Choose the Right Archive
Select repositories that match your data type and compliance needs.
- Use discipline specific repositories when available.
- Institutional repositories are appropriate for many data sets.
- Provide persistent identifiers for data and code deposits.
- Include metadata that describes variables and collection methods.
- Link archived files in the manuscript data availability statement.
Data Availability Statements
Each article should include a data availability statement outlining where data can be accessed, under what conditions, and who to contact if restrictions apply.
Embargo and Access Limits
Some data sets require controlled access or embargo periods due to privacy or institutional policies. Authors should describe these limitations clearly.
Data Management Expectations
A clear data management plan improves compliance and reduces delays during peer review.
Document Data Handling
Describe how data were collected, stored, de identified, and secured. Provide version control details for data sets and code when multiple updates exist.
Clinical Trial Data
For trials, specify which data are shareable, timelines for release, and any approvals required. This supports responsible reuse and regulatory alignment.
Permissions and Ownership
Authors retain rights to their data and may archive materials in repositories aligned with institutional or funder requirements.
Funder Compliance
Many funding agencies require data sharing or archiving. JCD supports compliance by allowing authors to deposit data in approved repositories and reference them in the published article.
Reuse and Attribution
Archived data should include clear licensing and citation instructions so other researchers can reuse materials responsibly and provide proper attribution.
Support Responsible Reuse
Clear citation and licensing helps other investigators build on chronic disease evidence without compromising ethical standards.
Persistent Identifiers
Assign DOIs or repository identifiers to archived data and code. This improves traceability, supports credit for data creators, and strengthens the reproducibility of published findings.
Reuse Conditions
Define reuse terms that protect participants while enabling scholarly collaboration. When data cannot be fully shared, provide clear access conditions and a contact pathway.
Protect Patients and Communities
Chronic disease research often involves sensitive health data. Ethical safeguards are mandatory.
- Remove direct identifiers and apply de identification standards.
- Confirm consent allows data sharing when required.
- Document ethics approvals and data governance policies.
- Use controlled access when risk of re identification exists.
- Include data use agreements for restricted data sets.
- State if data are available upon reasonable request.
- Describe any legal or contractual sharing limits.
- Provide repository access instructions for reviewers when needed.
- Ensure data sharing does not compromise participant safety.
