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

backgroundImplementation of dispatcher-assisted cardiopulmonary resuscitation (DACPR) has increased the likelihood of bystander CPR upon cardiac arrest. However, the quality of CPR has been found to be very low. In this study, we aimed to compare CPR quality between the current DACPR practices and the interventional instruction of adding verbal encouragement from the dispatcher.

methodsIn this randomized controlled trial, we recruited adult (age ≥18) laypersons who were non-health care providers and had never received any previous verified CPR training. They were randomly selected to perform DACPR using metronome sounds (mDACPR) as per the standard protocol, or DACPR with metronome sounds along with human encouragement (mheDACPR). The ratio of accurate compression rate, depth, and complete release for each CPR phase was examined.

resultsSixty nine records (34, mDACPR; 35, mheDACPR) were taken. The median proportion of accurate chest compression rate was initially 29.5% with mDACPR, and significantly increased to 71% after 2 minutes of CPR administration (P = .046). However, the median ratio of accurate chest compression depth was 61.5% in the first phase, and significantly decreased to 0% in the last phase (P < .001). In contrast, for the mheDACPR group, a high accurate compression rate was maintained throughout the 2 minutes of CPR administration (91%, 100%, 100%, 100%).

conclusionTo maintain the quality of CPR administered by bystanders, continuous feedback and repeated human encouragement should be provided during DACPR. Active dispatcher intervention reduces the time required to reach an appropriate CPR rate and allows for the maintenance of accurate compression rates.
