Data sharing statements: impact of journal policies across clinical research disciplines
- Cross-sectional study
Authors' conclusion
Data sharing statement inclusion in cardiology research remains inconsistent, with journal policies playing a key role in increasing prevalence. However, real-world data-sharing practices often fall short of stated commitments.
Study context
- Population
- Clinical studies published 2020–2023 in top cardiology, selected general medicine, emergency medicine and orthopaedic surgery journals
- Participants
- 2,941 articles
- Exposure
- Data sharing statement (DSS) inclusion across clinical research disciplines
- Outcome
- Prevalence of data sharing statement (DSS) inclusion
Main finding
As reported in the abstract
DSS inclusion
- Articles including a DSS (all disciplines)
- 1004 (34.14%)
Observational data: associations, not effects.
Further findings
Factors associated with DSS inclusion
- Post-policy articles significantly more likely to contain a DSS
- Funding status, study design, article access and impact factor also influenced DSS presence
- Dominant DSS themes: conditional availability and gatekeeping
Data provided by authors stating availability upon request
- Authors who ultimately provided access
