Swallow-induced syncope after magnetic sphincter augmentation: a case report and physiologic explanation.
Article in Clinical journal of gastroenterology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
Swallow-induced syncope is a rare cause of syncope that occurs during or immediately after swallowing. This phenomenon has been reported in association with few esophageal pathologies and the likely explanation is a vagal reflex during deglutition that results in inhibition of the cardiac conduction system. This report describes a case of swallow-induced syncope related to the implantation of a magnetic sphincter augmenting (MSA) device. Two episodes of syncope after food bolus occurred with the device in place and upon removal of the device, the patient had no further episodes of syncope. Vagal stimulation from distention of the esophagus or vagus nerve contact irritation by the implant are the potential explanation for syncope in this patient. Although this is an extremely rare complication of magnetic sphincter device augmentation, it is one that physicians should be cognizant of given the dangers of syncope events.
