Association of Racial Residential Segregation and Survival After Out-of-Hospital Cardiac Arrest in the United States.
Observational study 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
backgroundSocial determinants of health such as residential segregation have been identified as drivers of disparities in health outcomes; however, this has been understudied for out-of-hospital cardiac arrest (OHCA). We sought to examine whether there were differences in survival to discharge and survival with good neurological outcome, as well as likelihood of bystander cardiopulmonary resuscitation, using validated measures of racial, ethnic, and economic segregation.
methodsWe conducted a retrospective observational study using data from the Cardiac Arrest Registry to Enhance Survival data set. The primary predictor for this study was the Index of Concentration at the Extremes. The primary outcomes were survival to discharge and survival with good neurological status.
resultsDuring the study period, 626 264 had an out-of-hospital cardiac arrest, and patients had a mean age of 62 years (SD 17.2 years). In multivariable models, we observed an increased likelihood of survival to discharge and survival with good neurological outcome for those patients residing in more highly segregated predominately White population and higher-income census tracts as compared with more highly segregated and lower-income Black and Hispanic/Latinx population census tracts. We found that the magnitude of this disparity was 24% for the outcome of survival to discharge as compared with reference (relative risk,1.24 [95% CI, 1.20-1.28]).
conclusionsThis research suggests that areas impacted by residential and economic segregation are important targets for both public policy interventions as well as addressing disparities in care across the chain of survival for out-of-hospital cardiac arrest.
