Projected Cognitive and Brain Aging Benefits of Eliminating Cardiometabolic Risks in Non-Hispanic White and Black Males - HABS-HD.
Article in Journal of racial and ethnic health disparities, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundCardiometabolic risk factors contribute to cognitive decline and cerebrovascular pathology and are more prevalent among non-Hispanic Black (NHB) adults than non-Hispanic White (NHW) adults, with the greatest burden observed in males.
methodsWe analyzed 974 male participants (581 non-Hispanic White [NHW], 393 NHB) from the Health and Aging Brain Study – Health Disparities baseline visit. Multivariable linear regression models were used to examine associations between cardiometabolic risk factors, including hypertension, diabetes, dyslipidemia, obesity, and tobacco dependence, and outcomes of cognitive domain performance (memory, executive function, processing speed, and language) and white matter hyperintensity (WMH) burden, adjusting for age, education, apolipoprotein ε4 status, and race. Population intervention models (PIM), a counterfactual regression-based approach, were applied to estimate projected changes in cognition and WMH burden under hypothetical scenarios in which individual cardiometabolic risk factors were absent, with analyses stratified by racial ethnicity and mutually adjusted for the other cardiometabolic risks.
resultsDiabetes was associated with lower memory (β = − 0.14, 95% CI: − 0.27 to − 0.01) and language (β = − 0.15, 95% CI: − 0.29 to − 0.02). Tobacco dependence was linked to poorer performance across all domains (β range = − 0.20 to − 0.29). Hypertension was associated with greater WMH volume (β = 0.61, 95% CI: 0.09 to 1.12). PIM analyses projected memory gains from eliminating diabetes of 0.027 (95% CI: 0.002–0.052) in NHW and 0.039 (95% CI: 0.004–0.075) in NHB males, and gains from eliminating tobacco dependence of 0.015 (95% CI: 0.004–0.027) and 0.056 (95% CI: 0.017–0.098), respectively. Removing hypertension was projected to reduce WMH by − 0.394 (95% CI: − 0.769 to − 0.014) in NHW and − 0.481 (95% CI: − 0.940 to − 0.018) in NHB participants.
