Spontaneous pneumomediastinum: an uncommon clinical problem with a potential for missed or delayed diagnosis.
Article in BMJ case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
A 15-year-old man presented with an acute history of facial swelling following a bout of forceful eructation after eating. Subcutaneous emphysema was noted on examination of his left face and neck. He was initially managed with intravenous antibiotics for suspected facial infection. A chest radiograph performed on day 3 of admission identified subcutaneous emphysema of the upper thorax and neck. CT with oral contrast confirmed extensive subcutaneous emphysema of neck, thorax and upper abdomen, with associated pneumomediastinum. The site of air leak was not identified. He subsequently underwent upper gastrointestinal endoscopy and this was normal. Despite the delay in diagnosis, he remained haemodynamically stable, and repeated radiography showed improvement reflecting the benign course of this condition as described in existing literature. There are no previous published reports of spontaneous pneumomediastinum following eructation; therefore, high clinical suspicion should be maintained in this presentation.
