期刊政策鼓励或强制作者提供数据可用性声明，这越来越多地反映了使研究结果公开和可复制的努力。因此，在最近的文献中，数据可用性声明被大量采用。然而，目前尚不清楚这些声明中有多大比例实际上包含格式良好的数据链接，例如通过URL或永久标识符，以及提供这种链接是否有附加值。以PLOS和BMC发表的531 889篇期刊论文为研究对象，根据其内容和数据可用性类型，开发了一个自动标注系统，将其数据可用性声明分为4类，并通过回归分析了不同声明类别的引文优势。我们发现，在强制性的出版商政策下，数据可用性声明变得非常普遍。2018年，21，793篇PLOS文章中的93.7%和31，956篇BMC文章中的88.2%有数据可用性声明。包含到存储库中的数据的链接的数据可用性声明（而不是根据请求提供或作为支持信息文件包含在内）只占总数的一小部分。在2017年和2018年，20.8%的PLOS出版物和12.2%的BMC出版物提供了包含存储库中数据链接的DAS。我们还发现，使用引用预测模型，包含链接到存储库中数据的语句的文章与平均高达25.36%（+/- 1.07%）的引用影响之间存在关联。我们讨论了这些结果对作者（研究人员）和期刊出版商的潜在影响，他们努力在存储库中共享他们的数据。我们所有的数据和代码都是可用的，以便复制和扩展我们的结果。
Efforts to make research results open and reproducible are increasingly reflected by journal policies encouraging or mandating authors to provide data availability statements. As a consequence of this, there has been a strong uptake of data availability statements in recent literature. Nevertheless, it is still unclear what proportion of these statements actually contain well-formed links to data, for example via a URL or permanent identifier, and if there is an added value in providing such links. We consider 531, 889 journal articles published by PLOS and BMC, develop an automatic system for labelling their data availability statements according to four categories based on their content and the type of data availability they display, and finally analyze the citation advantage of different statement categories via regression. We find that, following mandated publisher policies, data availability statements become very common. In 2018 93.7% of 21,793 PLOS articles and 88.2% of 31,956 BMC articles had data availability statements. Data availability statements containing a link to data in a repository-rather than being available on request or included as supporting information files-are a fraction of the total. In 2017 and 2018, 20.8% of PLOS publications and 12.2% of BMC publications provided DAS containing a link to data in a repository. We also find an association between articles that include statements that link to data in a repository and up to 25.36% (+/- 1.07%) higher citation impact on average, using a citation prediction model. We discuss the potential implications of these results for authors (researchers) and journal publishers who make the effort of sharing their data in repositories. All our data and code are made available in order to reproduce and extend our results.
