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

backgroundObstructive sleep apnea is related to increased systemic inflammation and arterial hypertension. We present a case of retropharyngeal hematoma without trauma und hypothesize that this could be caused by untreated obstructive sleep apnea. CASE PRESENTATION: A 47-year-old white woman with unilateral pharyngeal discomfort presented to our ear, nose, and throat clinic. She had no risk factors for the development of a spontaneous retropharyngeal hematoma, for example, hypertension or coagulation disorder. As she was overweight, the anamnesis included signs of obstructive sleep apnea such as snoring or breathing arrests during the night, which she denied. An endoscopic examination showed a submucosal hemorrhage of the posterior wall of her pharynx. Magnetic resonance imaging revealed a retropharyngeal hematoma without evidence of the injury of any blood vessel. A subsequent seven-channel polygraphy revealed a severe obstructive sleep apnea with an apnea-hypopnea index of 59.5 per hour. She was subsequently treated with auto-titrating continuous positive airway pressure resolving obstructive sleep apnea immediately. Two months after this episode she presented without any complaints.

conclusionIn consequence of this case we are convinced that an untreated obstructive sleep apnea can lead to retropharyngeal hematoma.
