Life-threatening tracheal leiomyoma presenting as acute respiratory failure masquerading as refractory asthma: A case report.
Article in Respiratory medicine 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
Primary tracheal tumors represent less than 1% of all pulmonary neoplasms, with endobronchial leiomyomas accounting for a minute fraction of benign airway lesions. Due to their slow growth and nonspecific clinical presentation, these tumors are frequently misdiagnosed as obstructive airway diseases, such as asthma. We report the case of a 27-year-old female with a 3-year history of progressive, treatment-resistant respiratory symptoms initially managed as severe asthma. Despite escalating medical therapy, her condition deteriorated, culminating in an emergency department presentation with fulminant acute respiratory failure. Chest computed tomography and subsequent rigid bronchoscopy revealed a smooth, well-encapsulated 1.9 cm pedunculated tracheal mass originating from the posterior membranous wall, causing 100% luminal obstruction. The tumor was successfully resected via bronchoscopic snare electrocautery and basket extraction, followed by argon plasma coagulation of the base. Histopathological and immunohistochemical evaluation confirmed a benign tracheal leiomyoma. Postoperatively, the patient experienced immediate, complete resolution of respiratory symptoms with no recurrence at her 3-month follow-up. Tracheal leiomyoma, though rare, can cause life-threatening central airway obstruction where timely imaging and bronchoscopic intervention are ultimately lifesaving.
