ReviewSleep & breathing = Schlaf & Atmung2015
A review of EPAP nasal device therapy for obstructive sleep apnea syndrome.
Review in Sleep & breathing = Schlaf & Atmung, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundExpiratory positive airway pressure (EPAP) nasal devices provide a new therapeutic option for obstructive sleep apnea (OSA).
methodsHere, we review the literature about treatment of OSA with EPAP, which has been shown to reduce the apnea/hypopnea index (AHI) and daytime sleepiness.
resultsPatients generally prefer EPAP to continuous positive airway pressure (CPAP), and there are no serious adverse effects from its use. Although CPAP more effectively improves sleep apnea, a recent study showed similar outcomes in symptom improvement using EPAP. Patients with mild to moderate OSA who do not tolerate CPAP are appropriate candidates for EPAP. However, there are few well-designed clinical trials that evaluate efficacy.
conclusionsMore studies are needed to assess the efficacy of and compliance with EPAP nasal devices, to define which patients will benefit from EPAP therapy, and to compare EPAP to other alternative OSA therapies.
