> If allocated to caffeinated coffee consumption, patients were encouraged to drink at least 1 cup of caffeinated coffee (or at least 1 espresso shot) and other caffeine-containing products every day as per their usual lifestyle
I tried to skim to figure out how much caffeine/ml was actually in the drinks, but seems the researchers don't know themselves either? Wouldn't there be a huge difference depending on the beans, how it's made and so on? 1 espresso can be made very strong with packed coffee, or it can be made very weak, "1 cup of caffeinated coffee" basically says nothing at all, unless I'm missing the true definition elsewhere in the paper.
