Idiopathic Upper Tracheal Stenosis Presenting With Progressive Stridor Managed by Endoscopic Balloon Dilatation: A Case Report.
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
Idiopathic subglottic and upper tracheal stenosis is an uncommon cause of progressive airway obstruction, predominantly affecting middle-aged women. We report the case of a female patient who presented with progressive stridor at rest over 12 months, without antecedent airway instrumentation or systemic disease. Flexible nasoendoscopy demonstrated irregular subglottic mucosa with airway narrowing, and computed tomography confirmed a 1.5 cm segment of circumferential mucosal thickening resulting in significant luminal compromise. Comprehensive autoimmune screening was negative, supporting an idiopathic aetiology. The patient underwent endoscopic balloon dilatation with adjunctive mucosal trimming, resulting in immediate symptomatic improvement. This case highlights the importance of thorough diagnostic evaluation and minimally invasive management of idiopathic upper tracheal stenosis.
