The impact of additional special emergency medical service units on non-traumatic adult out-of-hospital cardiac arrest outcomes in a high-resource metropolitan area.
Article in Resuscitation plus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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) requires an effective cardiopulmonary resuscitation (CPR) and emergency medical service (EMS) response, yet survival rates remain low at 8.0-11.3 %. Factors such as team size, training and leadership influence outcomes, but optimal strategies are debated. The Vienna EMS routinely deploys field supervisors (FISU) to improve the quality of care. The aim of this study was to assess their impact on OHCA outcomes. Methods: This retrospective observational study analyzed all consecutive adult non-traumatic OHCA cases in Vienna between 01/2019 and 12/2023, focusing on the impact of additional specialised units (FISU or supervising senior emergency physician) on cardiac arrest outcomes (ROSC rates, survival to hospital discharge, neurological performance). Statistical analysis used descriptive statistics, group tests, and logistic regression. Results: A FISU was present in 45.7 % of cases, and its presence improved outcomes significantly including any ROSC (40.6 % vs 26.3 %; OR 1.963, CI 1.773-2.172, p < 0.001), survived event (sustained ROSC) (30.6 % vs 20.6 %; OR 1.720, CI 1.542-1.918, p < 0.001), survival to discharge (10.6 % vs 8.3 %; OR 1.263, 1.072-1.487, p = 0.005) and CPC 1/2 (7 % vs 6.4 %; OR 1.034, CI 1.152-1.253, p = 0.037). Multivariate analysis confirmed that the presence of FISU had an independently positive effect (any ROSC: OR 1.616, CI 1.440-1.813, p < 0.001; survived event: OR 1.335, CI 1.180-1.510, p < 0.001). Conclusions: The presence of additional EMS special units like field supervisors can improve outcomes of non-traumatic out-of-hospital cardiac arrest in a high-resource metropolitan area.
