Community-Level Compact City Design, Health Care Provision, and Outcomes of Patients With 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
backgroundThe optimal scale of urbanization for stroke health care provision and the potential impact of compact city design on stroke outcomes remain unclear. We investigated the impact of zip code area-level compact city design using the walkability index (WI) and its mediators on stroke outcomes.
methodsThis nationwide retrospective study used data from patients with stroke from the J-ASPECT study (2017-2022). WI was calculated as the average of 3
resultsOverall, 555 296 patients (median age, 75 [interquartile range, 66-83] years; female, 42.5%) from 818 hospitals were included. Higher WI was significantly associated with decreased in-hospital mortality (odds ratio [OR], 0.94 [95% CI, 0.92-0.96]) and increased functional independence (OR, 1.03 [95% CI, 1.02-1.04]). The highest WI group was associated with decreased mortality, primarily mediated by management in intensive or stroke care units (proportion mediated, 0.46 [95% CI, 0.35-0.63]), and the highest WI group was associated with increased functional independence, mediated by short road distance to the hospital (proportion mediated, 0.30 [95% CI, 0.21-0.44]).
conclusionsZip code area-level compact city design was associated with decreased in-hospital mortality and increased functional independence. Compact city design at community level, even without large-scale urbanization, may contribute to improving stroke care provision and outcomes in increasingly urbanized societies.
