Data availability statements and data citations policy: guidance for authors
All manuscripts reporting original research must include a data availability statement. Authors are also encouraged to include formal citations to datasets in article reference lists where deposited datasets are assigned Digital Object Identifiers (DOIs) by a data repository.
This policy builds upon our long-standing policy on data availability, which requires that authors make materials, data, code, and associated protocols promptly available to readers without undue qualifications. The preferred way to share large data sets is via public repositories. For certain types of data, data sharing is mandatory. This policy does not introduce new data sharing mandates but aims to make the circumstances for data availability more transparent to readers.
