A Crunch That Spoke: An Atypical Presentation of Spontaneous Pneumomediastinum in an Elderly Male.
Article in Cureus, 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
Spontaneous pneumomediastinum is a rare, usually self-limiting, condition characterized by the presence of free air in the mediastinal cavity without any identifiable precipitating factor. We report the case of a 63-year-old man who presented with chest pain, chest tightness, and shortness of breath. The patient had no known comorbidities and no history of smoking or alcohol intake. On examination, the patient was found to have subcutaneous emphysema around the neck and chest progressing to the face and upper limbs and extending to the groin, with no external injuries. Crepitus was present, extending from the face to the abdomen, and Hamman's crunch was noted. Chest imaging revealed free air within the mediastinum, confirming the diagnosis of spontaneous pneumomediastinum. The patient was treated with high-flow oxygen via a non-rebreather mask, and the respiratory condition was closely monitored. A left-sided intercostal drainage tube was placed due to extensive subcutaneous emphysema. The patient gradually showed clinical improvement and was discharged following the resolution of pneumomediastinum.
