The data here isn't comprehensive enough to show a direct causal relationship. It's not clear if coffee drinking is warding off dementia, if the early stages of dementia are altering people's coffee drinking, or if there's a third unknown factor affecting both coffee intake and dementia risk.

Yes, it's just observational. And confounding variables are a thing too.
