@Tezcatlipoca thanks for checking! Be careful though: "This is an observational study, so no firm conclusions can be drawn about cause and effect[...]"

Also: "results of previous studies looking at this issue have been inconsistent"

I'm particularly sceptical regarding the relatively small size of the study. Out of not even 2k people, how many drink nearly a liter coffee per day?!

The study I found only had old Italians in it.
