Upper airway hematoma: An unusual presentation of acute upper airway obstruction.
Article in Respiratory medicine case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Acute upper airway obstruction secondary to supraglottic hematoma is a rare but life-threatening complication of oral anticoagulants, particularly with warfarin. Symptoms include sore throat, dysphagia, odynophagia, dysphonia, neck swelling, and dyspnea. We are reporting a case of an elderly male on warfarin therapy who developed acute upper airway obstruction due to spontaneous supraglottic hemorrhage. Commonly reported sites of spontaneous bleeding are the sublingual and retropharyngeal spaces.
