REM Sleep-Associated Asystole.
Article in JACC. Case reports, 2026. 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
backgroundRapid eye movement (REM) sleep-associated bradyarrhythmia syndrome is characterized by asystole or complete heart block during the REM phases of sleep. There are minimal reported cases in the literature. CASE SUMMARY: This is a case of REM-associated sinus pauses incidentally noted on a sleep study in a young, healthy patient. Despite an implantable loop recorder demonstrating continued nocturnal pauses of up to 9.5 seconds, the patient remained without daytime symptoms or pauses and was managed without a pacemaker. DISCUSSION: REM sleep-associated bradyarrhythmia syndrome is a rarely described and poorly understood phenomenon with minimal guidelines for management. It may be underreported given that it is often asymptomatic and incidentally noted on sleep studies. Close surveillance may be appropriate rather than pacemaker implantation in those patients who are without daytime symptoms.
