Societal Venn Diagram?

I was wondering if anyone had seen anything about overlap between antivaccers and antimaskers. I’ve briefly searched, not too hard yet, and all I seem to get is links to various articles on why vaccines or masks are good/bad etc. (Maybe a result of living in Idaho, Gateway to The Great Trumpwest, google is stupid sometimes)

Has there been any sort of study or research on any sort of correlation or overlap between these two groups?
