The linked Wikipedia "study" is this science daily article: https://www.sciencedaily.com/releases/2006/10/061012185602.htm https://www.sciencedaily.com/releases/2006/10/061012185602.h... And that article links back to this UFL press release. I've clicked every link I can find and there's not an actual, published study to be found anywhere: https://archive.news.ufl.edu/articles/2006/10/uf-experts-decaffeinated-coffee-is-not-caffeine-free.html https://archive.news.ufl.edu/articles/2006/10/uf-experts-dec... But even if there was, is a study from 20 years ago still relevant?
