physical · Outcome
Keeping resting blood pressure in the healthy range (<120/80). Small absolute shifts (a few mmHg) compound over years into meaningful cardiovascular risk changes.
How to measure: Home cuff, morning + evening, average over a week. Single readings are noisy.
Three levers, one stack. Each works through a different mechanism. They compound.

“Inorganic nitrate and beetroot juice supplementation has a minimal effect on diastolic blood pressure (-1.1 mm Hg), which is not statistically significant.”
Why: Nitrate → nitric oxide → vasodilation. Effect is robust across trials. Side effect: pink urine (harmless). Works best alongside DASH-style diet.

Every pick has two signals. They answer different questions and we never bundle them into one number.
Effect size
How big is the change on blood pressure regulation, in the units that matter for this outcome.
Confidence
How sure are we the effect is real for blood pressure regulation, given the studies we have.
For every pick, the “papers” number is how many studies we've cataloged that test this entity for blood pressure regulation. “Favorable” means the study reported the direction you want.
The tier badge (S, A, B…) on the entity itself is its overall research confidence across all outcomes. It's the same letter wherever you see this entity on the site, not specific to blood pressure regulation.

“Resistance exercise training significantly reduces systolic blood pressure in patients with type 2 diabetes.”
Why: Aerobic + resistance both work; combined is best. Effect appears within weeks and is maintained as long as training continues.
