Without understanding of a mechanism we're still talking about correlation, though. Just one backed up by a metastudy.

- eyelidlessness 5y agoNot knowing the cause doesn’t mean much, in terms of valid association, unless the effect deviates as people adopt the correlating behavior. If we don’t know the mechanism but it continues to produce the same result absent other unrelated factors, it’s likely in the chain or determining factors.
- DennisP 5y agoI saw a study like that a year or two ago. It wasn't just correlation, they did an actual clinical trial. They measured BP before intervention, had people do a specific exercise to increase hand strength, had a control group, and measured everybody afterwards.
