Which sort of affirms the mantra, "If you can't prove causation, try to prove correlation." This because you can market correlation to unsophisticated readers and imply causation.

There’s already tons of correlation published for semaglutide lowering rates of dementia. This study is an effort at helping find the mechanism beyond the generally also known correlation that losing weight lowers rates of dementia.

Or, less conspiratorially, if correlation can be proven and causation is plausible but unproven, there may be benefits.

Proving correlation but not causation does NOT rule out causation.
