Disparities in Geographic Access to Cardiac Rehabilitation Among Socially Vulnerable Communities.
Article in Journal of the American Heart Association, 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
backgroundThere is a dearth of research examining geographic disparities in access to cardiac rehabilitation (CR). We evaluated whether disparities in geographic access to CR exist among socially vulnerable communities, using the Social Vulnerability Index (SVI).
methodsAmong 3113 US counties, we investigated relationships between SVI and number of hospitals with CR per 100 000 adults, modeled with SVI as a linear variable, and SVI and distance to the nearest county with CR facilities, modeled using spline terms for SVI. We used multivariable zero-inflated negative binomial regression modeling adjusted for county population, CR eligibility, percentage without health insurance, metropolitan status, and availability of existing health care infrastructure. We explored whether these relationships changed in the context of rurality.
resultsAfter adjustment, as SVI increased by 1 percentile, number of hospitals with CR per 100 000 adults decreased by 1.2% (
conclusionMore socially vulnerable communities experienced worse geographic access to CR facilities. This access disparity intensified in rural communities. Our findings call for reducing barriers to CR access among socially vulnerable and rural communities, potentially through virtual or hybrid models of CR.
