From association to understanding

Three connections.
Different kinds of evidence.

“Connected” can mean many things. Select a pathway to see what was studied, what was found, and where the clinical conclusions stop.

01 / Human association + clinical trial

An association worth understanding. An outcome still to prove.

Periodontitis is associated with atherosclerotic cardiovascular disease. A randomized trial of 120 patients found improved endothelial function six months after intensive periodontal treatment.

What it does not tell us

Endothelial function is an intermediate measure. This does not establish that periodontal treatment prevents heart attacks or strokes.
