Comparison of a Vibrating Belt Versus a Positional Pillow for the Treatment of Positional Obstructive Sleep Apnea in a Real-World Setting: Results of a Prospective Randomized Crossover Trial.

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
purposeObstructive sleep apnea (OSA) is a treatable global health concern with increasing prevalence, driven by the obesity epidemic and the aging population. Unfortunately, approximately one-third of patients are non-adherent to long-term treatment. This highlights the importance of identifying those with positional obstructive sleep apnea (POSA), which affects 25%-35% of the OSA population, as these patients may benefit from alternative therapeutic interventions such as vibrating positional devices or positional pillows. The aim of this prospective randomized crossover study was to assess the efficacy of two different positional therapies (PTs): a positional pillow (Posiform®) and a vibrating belt (Somnofit-belt®), for reducing supine sleep time in POSA patients in the home setting.
methodsAdults with POSA (n=102), diagnosed by polysomnography (PSG) at two university hospitals, were screened, and 19 patients met the criteria for at-home supine sleep and were included. Patients were randomized to use either the vibrating belt first and then the pillow, or the reverse. Patient questionnaires were used to assess sleep quality and comfort, and the Somnibel Pro® device was used to assess patients' sleep position.
resultsA statistically significant reduction in supine sleep time was observed in patients using the vibrating belt compared to baseline (p = 0.0001). No difference was observed for the pillow. There was no significant difference in sleep quality or comfort between the devices. This study also highlights the observation that supine sleep is infrequent in the home setting.
conclusionsIn this study, we have shown a significant reduction in supine sleep time in POSA patients using the vibrating belt, which was not observed with the positional pillow. However, the results must be qualified by the small number of patients included.
