KJCN encourages data sharing wherever possible to promote openness, transparency, and reproducibility of research. Subject to ethical and legal considerations, authors are encouraged to:

• Upload research data during the submission process; otherwise, share research data in a relevant public data repository with DOI for the data location.
• Include a data availability statement linking to the data. If it is not possible to share the data, use the statement to confirm why it cannot be shared.

KJCN accepts the ICMJE Recommendations for clinical data sharing statement policy (http://www.icmje.org/recommendations/). Authors may refer to the editorial, “Data Sharing Statements for Clinical Trials: A Requirement of the International Committee of Medical Journal Editors,” in J Korean Med Sci 2017;32:1051-3 (https://doi.org/10.3346/jkms.2017.32.7.1051).
