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.

2 · The registry

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: The HeartRunner trial was an investigator-initiated, randomized clinical controlled trial (RCT) examining whether community first responders (CFRs) activated through a smartphone application can improve survival after out-of-hospital cardiac arrest (OHCA). Objectives: The study compared standard care alone versus standard care with the addition of dispatched CFRs for patients with OHCA. Methods: The trial was conducted in the Capital Region of Denmark, with a catchment area of approximately 1.9 million inhabitants. By May 2019, 15,401 citizens had registered to serve as CFRs (837/100,000 inhabitants) and roughly 6200 automated external defibrillators (344/100,000 inhabitants) were publicly accessible in the study area (2.4 defibrillators per km
