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

Ludwig's angina is a rapidly progressive and life-threatening medical emergency. The mortality rate is about 8%. Management of the difficult airway in Ludwig's angina has been challenging for clinical physicians. We reported an otherwise healthy 49-year-old female, who visited our emergency department with progressive swelling of her chin, drooling, and dyspnea. Ludwig's angina with impending airway compromise was promptly identified. The precise anatomy of the distorted neck was accessed using ultrasound as an adjunct. Emergent tracheostomy was then established successfully within minutes. Physicians should consider using ultrasound as an adjunct to define anatomy before performing emergent surgical airways.
