This paper is not on sci-hub. :( The abstract sounds correlational. The quotes from the researchers at the top of the article say explicitly that it's casual.

This paper is not on sci-hub. :( The abstract sounds correlational. The quotes from the researchers at the top of the article say explicitly that it's casual. The later parts of the article describing the paper go back to sounding correlational. . I would expect there to be enough shared causes to make it rather a pain to untangle.
