Evaluating the Attenuation of Black-White Disparities in Cardiovascular Disease Incidence and Total Mortality by Life's Essential 8.
Article in Circulation. Population health and outcomes, 2026. 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
backgroundHigher cardiovascular health, as measured by the Life's Essential 8 (LE8) score, is associated with better health outcomes. We sought to examine whether higher cardiovascular health may attenuate racial disparities in cardiovascular disease (CVD) and total mortality.
methodsIn this cross-sectional analysis, we used data from Black and White participants aged 20 to 59 years in the Cardiovascular Lifetime Risk Pooling Project, based in the United States including data from 1985 to 2022, for whom LE8 scores (0-100 points, higher is better) could be calculated. We compared incidence rates and hazard ratios (adjusted for age, sex, and education) for CVD and mortality between Black and White participants. We estimated the quantitative reduction in Black-White hazards without versus with adjustment for LE8 score by examining proportional changes in beta coefficients.
resultsAmong 20 618 participants (28.6% Black; 54.8% women; mean age 45.9±11.6 years) followed for 499 000 person-years, 4316 developed CVD and 5660 died. The mean LE8 score was 61.5±14.7 for Black and 66.4±14.3 for White participants. Among Black participants, 1384 (23.4%) had a CVD event and 1870 (31.7%) died, compared with 2932 (19.9%) and 3790 (25.8%) of White participants, respectively. Black adults had higher hazards for incident CVD (adjusted hazard ratio, 1.55 [95% CI, 1.45-1.66]), which decreased to 1.20 (95% CI, 1.12-1.29) with LE8 adjustment, representing a 58.1% reduction in the beta estimate. Blood pressure score was the LE8 component associated with the greatest reduction in the beta estimate (47.7%). Findings were similar for mortality analyses (adjusted hazard ratio, 1.59 [95% CI, 1.50-1.68]).
conclusionsIn young and middle-aged adults, adjustment for LE8 score partially attenuated Black-White disparities in CVD events and mortality. Improving cardiovascular health from young adulthood could be an important strategy for reducing racial disparities.
