However, the study stops short of proving cause and effect. The participants were only asked about their coffee drinking habits once, at the start of the study period, and this wasn’t monitored over time.

And they were followed for a median of 13 years.

This is a terrible fucking study. 13 years is a huge amount of time and people’s habits change constantly.

Someone could have easily started out drinking 5 cups a day and in 13 years be drinking no coffee at all.

Makes all their data invalid as far as I’m concerned. They could have at least made 1 single follow up survey at the end to check if their drinking habits had changed. Jeez…

I don’t know rowrow, I’ve been consuming coffee in the same amount and much the same way for well over 20 years.
