Urban-rural disparities in out-of-hospital cardiac arrest outcomes: a nationwide Hungarian study.
Article in Resuscitation plus, 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
Background: Out-of-hospital cardiac arrest (OHCA) outcomes often differ between urban and rural settings, but comprehensive nationwide data from Central-Eastern Europe using uniform data collection and modern confounding control remain limited. We investigated urban-rural disparities in OHCA outcomes in Hungary. Methods: We analysed 130,258 OHCA cases (2018-2023) from the Hungarian National Ambulance Service registry, classified as urban (70.1 %) or rural (29.9 %) using national administrative categories. The primary outcome was on-scene return of spontaneous circulation (ROSC). We performed univariable and multivariable logistic regression, propensity score matching (PSM) and continuous response-time modeling using natural cubic splines. Results: The overall ROSC rate was 9.1 % (urban: 9.4 %, rural: 8.3 %, p < 0.001). After PSM, urban location remained significantly associated with higher survival (OR = 1.26, 95 % CI 1.20-1.32, p < 0.001). EMS response times were significantly longer in rural areas (median 14.9 vs 9.8 min, p < 0.001). Urban survival advantage was most pronounced in cases with shockable rhythms (OR = 1.57, 95 % CI 1.43-1.72), medical-witnessed arrests (OR = 1.31, 95 % CI 1.20-1.42), and response times ≤8 min (OR = 1.59, 95 % CI 1.44-1.76). Conclusions: Significant urban-rural disparities in OHCA on-scene ROSC persist even after accounting for patient and arrest characteristics. These findings highlight the need for targeted interventions to strengthen the Chain of Survival in rural communities.
