1 · What the graph read from it

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.

Abstract

Aim: Several countries worldwide have implemented systems to alert community first responders (CFR) via smartphone applications to increase likelihood of survival after out-of-hospital cardiac arrest (OHCA). Substantial heterogeneity across CFR systems has been reported but recent reports are lacking. The European Resuscitation Council (ERC) conducted a survey to characterise and compare CFR systems focusing on requirements for joining CFR programs. Methods: An online survey with 28 questions regarding general system description, CFR qualification and training was conducted using SurveyMonkey between October 2024 and January 2025. The survey was shared via QR-code at the ERC Congress 2024, e-mail invitations to all ERC national resuscitation councils, the ERC Guidelines 2025 webpage, ERC social media, ERC newsletter, and personal e-mail invitations to research groups and CFR systems. Results: Thirty-five CFR systems from 19 countries participated in the survey. The majority of CFR systems (69%, Conclusions: There are multiple CFR systems with a high degree of heterogeneity regarding minimum required CFR qualification and training as well as alerting modalities. Understanding these differences across systems is paramount to design studies to test the effect of CFR on patient outcomes.
