Relations of Life's Essential 8 Score with Arterial and Microvascular Function: The Jackson Heart Study.
Article in medRxiv : the preprint server for health sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Cardiovascular disease (CVD) poses a major burden on the US population, disproportionately impacting African Americans. Vascular function provides a window to assess cumulative risk predisposing individuals to adverse cardiovascular events. The American Heart Association (AHA) Life's Essential 8 (LE8) provides a means of scoring cardiovascular health, but has yet to be correlated with vascular function. Methods: In a sample of Jackson Heart Study participants (N=2,186, mean age 57 years, 65% women), LE8 scores were calculated per AHA guidelines at baseline visits (2000-2004). Noninvasive vascular assessments using arterial tonometry and Doppler ultrasound were performed within an ancillary study (2012-2017). Tests measuring aortic and peripheral arterial stiffness included carotid-femoral pulse wave velocity, carotid brachial pulse wave velocity, carotid-radial pulse wave velocity, central pulse pressure, forward pressure wave, and characteristic impedance. Microvascular function tests included baseline and hyperemic brachial artery flow. Linear regression models, adjusted for age, age Results: In adjusted models, higher LE8 scores were associated with lower carotid-femoral pulse wave velocity (β= -0.32; 95% confidence interval (CI), [-0.42, -0.21]; Conclusions: Our cross-sectional findings support the concept that a healthy lifestyle is associated with better vascular function. Future longitudinal studies are warranted to investigate whether improving LE8 scores lead to improved vascular function.
