Postpartum Transient Hypervagotonic Sinus Node Dysfunction Leading to Sinus Bradycardia: A Case Report.
Article in Cureus, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Sinus bradycardia is common in children and adults, especially during sleep. The heart rate can drop below 30 beats per minute. Up to 35% of healthy individuals below 25 years of age, trained athletes, and those with a rare form of the familial syndrome with potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 4 (HCN4) mutation may have asymptomatic sinus bradycardia without any heart diseases. The increased vagal tone has been associated with profound bradycardia in various pathophysiologic settings including pain. Herein, we report the first case of a young Caucasian female with transient symptomatic bradycardia due to postpartum hypervagotonic sinus node dysfunction (SND).
