From the NCBI Insights Blog:
In the NLM Strategic Plan released earlier this year, we noted that “[c]reating efficient ways to link the literature with associated datasets enables knowledge generation and discovery.” To that end, PMC is now aggregating data citations, data availability statements and supplementary materials, as available, in an Associated Data box. This box will only display on articles that have one or more of these features in the article.
To limit your search to records with an Associated Data box, you can use the new “Associated Data” facet on the search results page.
