Prehospital 12-Lead ECG Use for Suspected Acute Coronary Syndrome Varies by Community Social Vulnerability.
Observational study in Prehospital emergency care, 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
objectivesTo examine the association of community-level social drivers of health with variability in the documentation of prehospital 12-lead electrocardiogram (ECG) for patients with suspected acute coronary syndrome (ACS).
methodsThis retrospective observational cohort study was conducted using the 2021 ESO Data Collaborative with de-identified records from more than 1,300 emergency medical services (EMS) agencies in the United States. We included 9-1-1 ground responses for adults ≥35 years with a prehospital clinical impression of ACS who were transported to the hospital. Social vulnerability index (SVI) was linked at the Census tract of the scene encounter and grouped in quartiles with the highest quartile representing communities of greatest vulnerability. The primary outcome was documentation of prehospital 12-lead ECG performance. Multivariable logistic regression models were used to examine the association of SVI with prehospital 12-lead ECG documentation of performance.
resultsAmong 34,388 EMS encounters for patients with suspected ACS, 73% were between the ages of 45-79 years old, 49% were female, and 18% were Black. Most calls occurred in the South (64%), with a paramedic crew (90%), and 29% were in rural settings. Compared to communities in the least vulnerable quartile, Q2 (OR 0.86, 95%CI 0.78-0.95,
conclusionsHigher community social vulnerability was significantly associated with lower odds of prehospital ECG for patients with suspected ACS, suggesting that additional resources focused on these communities may be needed to address these inequities.
