1 · What the graph read from it

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.

2 · The registry

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

Giant thyroid masses causing prolonged tracheal compression may lead to severe tracheomalacia, where progressive erosion of cartilaginous rings renders the trachea smooth, featureless, and difficult to distinguish from the esophagus during bronchoscopy. This poses a significant risk during awake fiberoptic intubation. Such airway distortion requires heightened vigilance, meticulous endoscopic assessment, and confirmation of tracheal entry to prevent misplacement. Early recognition and a systematic airway strategy are crucial for optimal patient safety and outcomes.
