Exploring the role of drug-induced sleep endoscopy in optimizing upper airway stimulation therapy for non-responders.
Article in Sleep & breathing = Schlaf & Atmung, 2025. 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
purposeUpper airway stimulation by means of unilateral hypoglossal nerve stimulation is an alternative therapy for patients with obstructive sleep apnea and continuous positive airway pressure intolerance or failure. Optimal device settings are essential for effective treatment of obstructive sleep apnea with this therapy. Some patients experience therapy failure, despite standard titration methods. We perform a drug induced sleep endoscopy with upper airway stimulation in these patients. This study provides an overview of this procedure and our patient outcomes.
methodsRetrospective chart review of patients implanted with an upper airway stimulation device between 2015 and 2022.
resultsThe drug-induced sleep endoscopy with upper airway stimulation therapy is performed in 29 non-responders of therapy. In seven patients, a change in device settings was sufficient to prevent an upper airway collapse during the drug-induced sleep endoscopy, while additional therapy was recommended for the remaining. Eventually, six patients were fitted with a change in device settings and fourteen patients were treated with additional therapy, being oral appliance therapy, barbed wire pharyngoplasty or alternative upper airway surgery. At follow-up, the apnea-hypopnea index declined significantly from 41.6 ± 15.0 to 23.2 ± 9.9 events/hour and resulted in eight additional responders to therapy.
conclusionThe drug-induced sleep endoscopy might be a valuable addition in the clinical pathway of upper airway stimulation therapy. It provides a better evaluation of the stimulation process and offers the opportunity for alterations in settings or targeted additional therapy.
