Mediating Effect of Established Risk Factors on Association Between Social Determinants and Cardiovascular Disease Mortality.
Article in JACC. Advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundSocial determinants of health (SDOH) contribute to increased cardiovascular disease (CVD) mortality.
objectivesThe authors investigated the mediating effects of behavioral and clinical risk factors in the association between SDOH and CVD mortality.
methodsA total of 50,808 National Health and Nutrition Examination Survey participants aged ≥20 years were included in this analysis. Data on social, behavioral, and clinical risk factors were collected in each National Health and Nutrition Examination Survey, and CVD deaths were ascertained through linkage to the National Death Index with follow-up through 2019. Multiple mediation analysis was used to examine the contributions of behavioral and clinical risk factors to the SDOH-CVD mortality association.
resultsThe mean age of participants was 47.2 years, and 48.8% were male. A dose-response association between the number of SDOH and CVD mortality was identified. Individuals with a composite SDOH score ≥ median have a 2.13-fold increased risk of CVD mortality (95% CI: 1.91-2.37) compared to those with a score < median. After adjusting for behavioral and clinical risk factors, the HR was reduced to 1.67 (95% CI: 1.50-1.86). Current smoking (relative contribution 11.4%; 95% CI: 8.1%-14.8%), physical inactivity (7.7%; 95% CI: 4.9%-10.6%), chronic kidney disease (5.5%; 95% CI: 3.8%-7.1%), diabetes (2.0%; 95% CI: 1.1%-2.9%), and unhealthy sleep duration (1.8%; 95% CI: 0.3%-3.3%) significantly mediated the association between CVD mortality and unfavorable SDOH. In aggregate, behavioral and clinical risk factors mediated 30.8% (95% CI: 24.2%-37.5%) of the overall CVD mortality attributable to unfavorable SDOH.
conclusionsBehavioral and clinical risk factors partially mediate the association between unfavorable SDOH and increased CVD mortality.
