1 · What the graph read from it

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.

2 · The registry

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

backgroundWe sought to examine the relationship between patient race/ethnicity and presentation to an emergency department (ED) with acute stroke capabilities, and whether this varied by rurality and telestroke access.

methodsAll acute ischemic stroke encounters in California in 2021 were obtained from California Department of Health Care Access and Information data. ED capabilities were from the 2021 National ED Inventory-USA database. Acute stroke capability was defined as having acute stroke ready status (or higher), telestroke or both. We examined the association between race/ethnicity and presentation to an ED with acute stroke capabilities, overall and stratified by rurality. Sensitivity analyses removed telestroke from our definition of acute stroke capability.

resultsIn 2021, 264 of 325 California EDs (81%) had acute stroke capabilities, 41 (13%) via telestroke alone. Only 2,050 of 63,252 encounters (3%) presented to an ED without capabilities. Rural (versus urban) patients had lower odds of access to acute stroke capabilities, regardless of telestroke status. There were no differences in access by race/ethnicity for rural patients, but urban Hispanic, non-Hispanic Black and patients of other race had lower odds of access (versus urban non-Hispanic Whites) regardless of telestroke status.

conclusionsMost California EDs have acute stroke capabilities. While few patients presented to non-capable centers, rural patients had lower odds of access. Racial/ethnic disparities differed between urban and rural settings, with lower odds of access for Hispanic and non-White urban patients but no significant differences by race/ethnicity in rural patients, however this latter finding might reflect limited power due to smaller sample sizes. ED telestroke capability did not reduce disparities in access.
