Using an audiovisual feedback device improves cardiopulmonary resuscitation performance during day and night - a randomized controlled simulation study.
Trial report in BMC emergency medicine, 2025. 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
backgroundSurvival of in-hospital-cardiac-arrests is lower when they occur at night and at weekends than when they occur during the day. Despite numerous studies, there is little evidence regarding the cardiopulmonary resuscitation quality at night and the influence of a feedback device depending on time of day. The present study investigates the differences between chest compressions at night and during the day, with and without the use of a feedback device.
methodsThe study was approved by the local Ethics Committee and registered in the German Clinical Trials Register on 22nd of February 2022 (DRKS00027309) prior to inclusion of the first participant. 158 medical professionals were randomized into one of two groups: "no feedback" and "feedback"-group. In both groups, participants carried out three two-minute intervals of cardiopulmonary resuscitation on a manikin at day and at night. Members of the "feedback"-group received guidance by a feedback device. Primary endpoint was the mean compression depth at two time-intervals at the beginning (t
resultsAt night, mean compression depth was significantly higher in the "feedback"-group at t
conclusionThe use of a real-time audiovisual feedback significantly improved compression depth during the day and night in a manikin-based simulation study with medical professionals.
