Efficacy of the New Generation of Devices for Positional Therapy for Patients With Positional Obstructive Sleep Apnea: A Systematic Review of the Literature and Meta-Analysis.

The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04086407 (The Effect of Head Pitch and Roll Rotation Independent of Torso Rotation on the AHI in Positional Obstructive Sleep Apnea), which is not on this map. Cited by 64 papers, 5 of them syntheses 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.

Abstract
STUDY
objectivesIn approximately 56% to 75% of patients with obstructive sleep apnea (OSA), the frequency and duration of apneas are influenced by body position. This is referred to as position-dependent OSA or POSA. Patients with POSA can be treated with a small device attached to either the neck or chest. These devices-a new generation of devices for positional therapy (PT)-provide a subtle vibrating stimulus that prevents patients adopting the supine position. The objectives of this study were to determine whether PT is effective in improving sleep study variables and sleepiness, and to assess compliance.
methodsA systematic review and meta-analysis.
resultsThree prospective cohort studies and four randomized controlled trials were included in this review. Combined data for studies reporting on the effect of PT show that there was a mean difference of 11.3 events/h (54% reduction) in apnea-hypopnea index and 33.6% (84% reduction) in percentage total sleeping time in the supine position. The standardized mean difference for both parameters demonstrated a large magnitude of effect (> 0.8 in both cases).
conclusionsThere is strong evidence that the new generation of devices for PT are effective in reducing the apnea-hypopnea index during short-term follow-up. These devices are simple-to-use for patients and clinicians and are reversible. Under study conditions with short-term follow-up, compliance is high; however, long-term compliance cannot be assessed because of lack of reliable data. Additional long-term, high-quality studies are needed to confirm the role of PT as a single or as a combination treatment modality for OSA patients and to assess long-term compliance.
