Differential Role of Multi-Dimensional Sleep Health on Cardiovascular Risk by Race and Ethnicity in U.S. Adults.
Article in Journal of racial and ethnic health disparities, 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
backgroundCardiovascular disease (CVD) disproportionately affects racial and ethnic minorities, and disparities in sleep health may significantly contribute to these inequalities. Historically, the lack of representation of minorities in sleep research, along with a narrow focus on specific sleep measures, has limited our understanding of the role of sleep health in CVD disparities.
objectivesThis study aimed to investigate racial and ethnic disparities in CVD risk and to explore whether a composite sleep measure, multidimensional sleep health (MDSH), mediates or moderates these disparities using nationally representative data.
methodsWe analyzed data for 5,098 adults ages 30 to 80 years without existing diagnosed CVD from the 2017-2020 National Health and Nutrition Examination Survey (NHANES). CVD risk was measured using the Framingham Risk Score (FRS). Multivariable ordinal logistic models examined associations between race and ethnicity with FRS, adjusting for covariates. We conducted tests of the mediating and moderating role of MDSH in these associations.
resultsAsians and Hispanics exhibited significantly lower odds of CVD risk compared to Whites. In contrast, Black and other race including multi-racial individuals showed no differences in CVD risk compared to Whites. MDSH did not significantly mediate differences in CVD risk by race/ethnicity. However, there was a moderating effect of MDSH, such that Asians and Hispanics had much lower CVD risk than Whites when they had ideal MDSH, while the same groups had similar CVD risk when MDSH was poor.
conclusionMDSH may play a different role in CVD risk, depending on race and ethnicity.
