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.

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

Video-assisted cardiopulmonary resuscitation (V-CPR) can improve the quality of bystander-performed CPR; however, its applicability has not been explored in situations where the lay responder is alone with the victim. This pilot study aimed to assess the feasibility of V-CPR in such scenarios. A randomized controlled crossover simulation study was conducted with 10 lay responders in two settings: a residential living room and a yard. Participants used available household objects to position a smartphone for a live video call with a dispatcher. The study evaluated (1) camera placement and perspective, (2) camera placement time, and (3) video quality and CPR assessability, based on assessors evaluations. No participant failed to establish a usable camera view. The average placement time was 23.4 s indoors and 34.0 s outdoors (p = 0.075). Based on five assessors, hand position and compression rate were highly assessable (86% and 84%), while compression depth was correctly assessed in only 32%. Although V-CPR quality varied between environments, the method proved feasible even when responders acted alone. Further studies are needed to compare the results with commercial V-CPR, optimize camera positioning, reduce delays, and evaluate outcomes using standardized dispatcher protocols. This study was retrospectively registered at https://clinicaltrials.gov/ ClinicalTrials.gov (NCT06794398, 01/27/2025).
