Unexpected Subglottic Stenosis Detected During Difficult Intubation for the Induction of General Anesthesia: 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
Subglottic stenosis presents with a wide spectrum of symptoms depending on the severity of the stenosis, which may remain completely asymptomatic and therefore escape routine preoperative evaluation. We report a seven-month-old girl who experienced unanticipated failed tracheal intubation despite an optimal Cormack-Lehane grade I laryngoscopic view. Multiple cuffless endotracheal tubes of progressively smaller sizes encountered identical resistance immediately below the vocal cords, while oxygenation and ventilation remained adequate. Recognizing the possibility of a fixed subglottic lesion, further intubation attempts were avoided. Airway management was safely achieved using a supraglottic airway device, allowing the procedure to proceed without hypoxemia or airway trauma. Postoperative bronchoscopic examination revealed whitish membranous stenosis in the subglottic area. This case underscores that optimal glottic visualization does not guarantee successful intubation in infants and highlights the importance of early recognition of fixed subglottic resistance, timely transition to supraglottic airway devices to prevent airway injury, and prompt bronchoscopic evaluation in unexpected pediatric difficult airways.
