Variation in Prehospital Routing Patterns for Patients With Suspected Stroke.
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
backgroundOur objective was to describe emergency medical services (EMS) transport destination practices for patients with suspected stroke using a novel linked data set of EMS patient care data and verified emergency department (ED) stroke-related capabilities.
methodsThis was a cross-sectional evaluation of EMS 9-1-1 encounters for patients with suspected stroke from 2019 to 2021 from the ESO Data Collaborative, linked to verified ED capabilities from the 2021 National ED Inventory-USA survey. Our primary outcome was transport to an ED with any stroke care capabilities. We used mixed effects logistic regression models with a random intercept for agency to estimate the odds of transport to an ED with stroke care capabilities. We used intraclass correlation coefficients and median odds ratios (ORs) to quantify the contribution of covariates and variability between EMS agencies.
resultsThe analytic sample included 314 642 encounters (median age 72 years, 53% female) from 1781 EMS agencies, including 719 (40%) agencies primarily serving rural areas. Overall, 32 142 (10%) patients were transported to facilities lacking verified stroke care capabilities. There was significant between-agency variation, with median ORs consistently >2.0 (eg, fully adjusted model, median OR, 3.91 [95% CI, 3.71-4.11]). Rural, versus urban, location was associated with lower odds of transport to an ED with stroke care capabilities (OR, 0.15 [95% CI, 0.14-0.17]).
conclusionsIn this analysis of EMS encounters, 1 in 10 patients with suspected stroke was transported to a facility without verified stroke care capabilities. Variation across EMS agencies and lower odds of appropriate routing in rural settings highlight critical gaps in prehospital stroke systems of care.
