Out-of-hospital cardiac arrest survival in Black & Hispanic communities since the COVID-19 pandemic.
Article in Resuscitation, 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
backgroundSurvival after out-of-hospital cardiac arrest (OHCA) decreased sharply in 2020 during the COVID-19 pandemic. It is unknown if survival recovered to pre-pandemic levels, or how recovery varied by community racial and ethnic composition.
methodsWe analyzed adults with non-traumatic OHCA from 2015 to 2022 in the Cardiac Arrest Registry to Enhance Survival using multivariable regression models with generalized estimation equations to calculate risk-adjusted rates of survival to discharge during 2015-2019 (pre-pandemic period) versus 2020, 2021, and 2022. We also examined survival rates based on community racial/ethnic composition, defined as predominantly White (≥80% White residents), majority Black or Hispanic (≥50% Black or Hispanic residents), or integrated (neither).
resultsThe cohort included 506,419 OHCA patients (mean age 61.9y; 64% male, 22% Black race, 7% Hispanic ethnicity). Pre-pandemic survival was 9.9%, with lower survival in majority Black/Hispanic (7.9%) and integrated (10.7%) versus predominantly White communities (11.1%). In 2020, survival decreased to 9.0% overall (relative change -9.1% vs pre-pandemic; P < 0.001), with a larger decrease in majority Black/Hispanic (-16.5%) than predominantly White (-8.1%) or integrated (-6.5%) communities (P for interaction: 0.07). Overall, survival rates remained largely unchanged in 2021-2022 (9.1%), with modest improvements in majority Black/Hispanic communities. However, absolute survival remained lower in these communities at all times compared to other communities.
conclusionsOHCA survival improved minimally in 2021 and 2022 following a significant decline in 2020. The initial decline was larger in majority Black or Hispanic communities; despite some improvement in 2021 and 2022, absolute survival in these communities remained lower throughout the study period.
