ASTRO Journals Data Sharing Policy

ASTRO does not require data sharing. In the interest of transparency and in support of Findable, Accessible, Interoperable, and Reusable (FAIR) data principles, however, authors are asked to include a data availability statement with their submitted work. Data availability statements should indicate if the data are being shared and if so, how the data may be accessed. Data availability statements will be published alongside articles submitted after this policy goes into effect (on January 1, 2020).

Along with its data sharing policy, ASTRO recently published a guide with recommended best practices for authors submitting to its journals. Read ASTRO Journals’ Data Sharing Policy and Recommended Best Practices, in Advances in Radiation Oncology.

Some of the topics covered include:

  • How to write a data availability statement
  • How to cite a dataset and get credit for published data
  • Choosing a data repository
  • Expectations in cases where data access is restricted

A free CME accredited activity based on the article is available through ASTRO Academy.

Advances in Radiation Oncology is a Gold open access journal, so authors, readers and patients have free access to all articles.

Data availability statement examples:

CategoryExample statement(s)Published in
All data availableClinical study reports, detailed data tables, and programming code are available on the Dryad Digital Repository (https://doi.org/10.5061/dryad.bv8j6) and at www.Study329.org/British Medical Journal
Patient level data for this study is available at: http://www.gsk-clinicalstudyregister.com/study/29060/329.GlaxoSmithKline Study Register
All data generated and analyzed during this study are included in this published article (and its supplementary information files). 
Third-party dataThis study was based on the English national cancer registry data. The authors do not own these data and hence are not permitted to share them in the original form (only in aggregate form, eg, publications). At the time of request data were provided by the Office for National Statistics but now all cancer registrations are owned and maintained by Public Health England.British Medical Journal
Data are available from the UK Biobank for researchers who meet the criteria and gain approvals to access the research database from the UK Biobank access management committee at the University of Oxford. Applications are reviewed and approvals granted subject to meeting all ethical and research conditions set forth by the UK Bio Bank. Information on access procedures, general enquiries, and contact information can be found online: https://www.ukbiobank.ac.uk/key-uk-biobank-contacts/. The full code for the analysis is available at: https://github.com/PRISM-UoN/UK-Bio-Bank-Machine-Learning-Project.PLOS One
Restricted access (commercial)Data for these analyses were made available to the authors through third-party license from Optum and Truven, 2 commercial data providers in the United States. As such, the authors cannot make these data publicly available due to data use agreement. Other researchers can access these data by purchasing a license through Optum and Truven. Inclusion criteria specified in the Methods section would allow other researchers to identify the same cohort of patients we used for these analyses. Interested individuals may see https://www.optum.com/solutions/prod-nav/product-data.html for more information on accessing Optum data and https://marketscan.truvenhealth.com/marketscanportal/ for more information on accessing Truven data.PLOS Med
Restricted access (legal/ethical)It is Novartis Policy not to share data from interim trial results, even if a Health Authority approval has been granted based only on interim trial data. Novartis will share data when the trial CSR is completed, and the results published.Clinical Study Data Request
