Neighborhood-Level Socially Determined Vulnerabilities and Outcomes After Heart Failure Hospitalization.
Article in Journal of the American Heart Association, 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
backgroundOutcomes are poor for older adults following a hospitalization for heart failure (HF). Neighborhood-level socially determined vulnerabilities could contribute to this, but this is not well studied. We aimed to determine associations between neighborhood-level socially determined vulnerabilities (density of clinical treatment facilities, physical activity facilities, and unhealthy food sources) and outcomes following HF hospitalization.
methodsWe included 366 Medicare beneficiaries in the REGARDS (Reasons for Geographic and Racial Differences in Stroke) cohort study aged ≥65 years and living in urban areas, who were discharged to home following HF hospitalization between 2003 and 2017. The main exposures were low versus high density (based on median) of clinical treatment facilities, physical activity facilities, and unhealthy food sources within 1 km of each participants' home. The primary outcomes were 90-day and 6-month composite of all-cause mortality or readmission.
resultsLiving in an area with high density of unhealthy food sources was associated with a 6-month composite of all-cause mortality and hospitalization (adjusted hazard ratio [aHR], 1.47 [95% CI, 1.09-1.98]). This was largely driven by readmission (aHR, 1.52 [95% CI, 1.12-2.07]). There were no associations between density of clinical treatment or physical activity facilities with outcomes at either time point.
conclusionsHigher density of unhealthy food sources in a participant's neighborhood environment is associated with worse outcomes after HF hospitalization among older adults living in urban environments. Neighborhood-level interventions, such as those that can mitigate exposure to unhealthy foods, may be important to improve posthospitalization outcomes in people living with HF.
