PubMed and PubMed Central (PMC) now offer filters to limit a search to only those articles or citations that include related data links, supplemental material, data citations, or a data availability or data accessibility statement.
The filters, detailed below, can be combined with any search by simply adding the Boolean operator “AND” and the specific filter into the search box (see the screenshots below for example syntax; the filters are highlighted in yellow).
Use data[filter] to find citations with related data links in either the Secondary Source ID field or the LinkOut – more resources field (both located below the abstract).
Data links could point to items such as the corresponding study record in ClinicalTrials.gov, or to locations for direct download of data through external data repositories such as figshare or Dryad, or through NLM databases such GEO or dbGaP.
