Geospatial disparities in emergency medical utilization and neighborhood-level socioeconomic status in Yamato City, Japan.
Article in Preventive medicine reports, 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
Objective: Neighborhood-level socioeconomic disparities are becoming more apparent in Japan; however, their relationship with emergency medical utilization remains unclear. Methods: This cross-sectional study was conducted in Yamato City, a suburban municipality near Tokyo. The city was divided into nine daily living districts based on the jurisdictions of Regional Comprehensive Support Centers. Demographic and socioeconomic indicators were obtained from municipal statistics for June 2025 and the 2020 national census. Data on 1199 ambulance transports, including 953 city residents, during secondary emergency duty from April 2024 to March 2026, were extracted from our hospital's medical records. Results: The proportions of residents aged ≥65 and ≥75 years, nursing care certification rate, welfare recipient rate, ambulance transport rate, emergency hospitalization rate, and areal deprivation index (ADI) showed a consistent north-south geographic gradient, with higher values in the southern area. Both ambulance transport and emergency hospitalization rates were positively correlated with ADI across the nine districts. The southern area had the highest ambulance transport rate for fall-related injuries, particularly among women. Conclusions: Neighborhood-level socioeconomic disadvantage was associated with ambulance transport and emergency hospitalization in a Japanese suburban city. Tailored public health strategies may help optimize the emergency medical care system in resource-limited settings.
