Why trials measure it. One of the most common outcomes in heart and diet trials, measured at rest or across a full day.

About this marker: Blood pressure measurement (MedlinePlus, U.S. National Library of Medicine).

Evidence states come from published human studies found in PubMed and OpenAlex and read by a model pipeline. "Not studied" means no usable human study was found for this marker, which is a gap, not a negative result. Every result links its studies so you can check it.
