JSDF strongly advocates for transparency, reproducibility, and openness in scientific research. According to the data and reproducibility of COPE, JSDF encourages authors to share associated data, code, and materials, register clinical trials, and use standardized guidelines to achieve greater transparency, replicability, and trust in scientific findings. Authors submitting manuscripts must ensure that all underlying data associated with their published research are readily accessible and clearly presented.
Manuscripts must accurately represent research data, with no manipulation, falsification, or omission of relevant findings. Authors are expected to provide sufficient methodological detail, including protocols, procedures, and materials, to allow independent replication of their study. Proper references supporting the methods and results must also be included.
Authors are encouraged to deposit their datasets in publicly accessible repositories, ensuring that readers and other researchers can access and verify the data. If public repository submission is not possible, authors must specify how the data can be obtained and any conditions governing access. A Data Availability Statement must be included in each manuscript, explicitly indicating the location and availability of the underlying data. Authors are encouraged to cite any datasets deposited in external repositories mentioned in their manuscript in the references. For previously published datasets, authors should cite both the published research article and the source of the dataset itself.
Supplementary materials such as statistical codes, analysis scripts, or additional methodological details that aid reproducibility should be submitted alongside the manuscript when appropriate. Authors must ensure that any shared data comply with applicable ethical guidelines, privacy standards, and data protection regulations.
Editors and reviewers may request access to data during the peer-review process to verify the findings and conclusions. Manuscripts lacking sufficient data transparency may be subject to revision or rejection. By adhering to this policy, JSDF promotes scientific rigor, transparency, and the credibility of published research.
