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
Introduction: Guidelines recommend 2-min rescuer rotations for high-quality cardiopulmonary resuscitation. However, 1-min cycles may improve performance. Their effectiveness in advanced cardiac life support, particularly with audiovisual feedback (AVF) devices, remains unclear. This study compares rotation strategies and AVF device use in a simulated advanced cardiac life support setting. Methods: In this randomized simulation study, resuscitation teams performed a standardized scenario using either 1- or 2-min chest compression rotations, with or without AVF guidance. Manikin-derived data, including compression rate, depth, and percentage of target-compliant compressions, were compared among the four study groups. Chest compression fraction, interruption time, and rescuer fatigue were also assessed. Results: A total of 31 participants performed chest compressions in this study. They were randomized to complete 10 simulated CPR sessions per group, resulting in data for 30 compressors per group. AVF use significantly improved compression depth and in-target performance in both 1- and 2-min rotation strategies (median 9.7% vs 52.8% in the 1-min no-AVF and with AVF, respectively; Conclusion: Without AVF, 1- and 2-min rotations showed comparable but suboptimal chest compression quality. AVF markedly improved performance across both strategies, with the 2-min rotation with AVF achieving the highest compression quality and chest compression fraction.
