Limits of this measure
National survey estimate for the civilian noninstitutionalized population. Sampling uncertainty and survey changes matter. A numerical difference alone does not establish statistical significance or policy causation. Includes measured blood pressure and medication use. It is distinct from self-reported diagnosed hypertension.
Daily source checks do not create new daily observations. Figures may be revised, and timing does not establish administration causation. This record is informational and should not guide financial or medical decisions.
