Variability of automated external defibrillator (AED) signage across six continents: a descriptive cross-sectional study.
Article in Resuscitation plus, 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
Background: Out-of-hospital cardiac arrests are associated with high mortality. Despite lay rescuer automated external defibrillator (AEDs) use being crucial for improving outcomes, public utilization of AEDs remains low. Signage characteristics directing lay rescuers to AEDs in public areas vary. We describe AED signage variability across six continents, focusing on shape, color, text, and symbols. Methods: A convenience sample of 120 publicly available online AED signage, collected between December 2024 and May 2025, was analyzed. Six continents were included: Europe (38.3%), North America (23.3%), Africa (14.2%), Australia (12.5%), Asia (7.5%), and South America (4.2%). Separately, 90 crowd-sourced images of airport AED signage were collected from 71 airports across six continents between January and November 2025: Europe (37.8%), North America (36.7%), Africa (1.1%), Australia (6.7%), Asia (15.6%), and South America (5.6%). We reported frequencies and proportions of signage characteristics for the samples and stratified by continent. Results: The distribution of signage characteristics in the publicly available signage varied across six continents ( Conclusions: There appears to be significant variation in public AED signage globally. Further research is needed to determine if specific signage characteristics improve AED recognition and utilization.
