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

purposeThis feasibility study examined the initial-use safety and effectiveness of a new noninvasive oral pressure therapy (OPT) system developed to treat obstructive sleep apnea (OSA).

methodsThe OPT system consists of a console that connects with flexible tubing to a premanufactured polymer mouthpiece. Through the mouthpiece, a pump in the console creates oral vacuum intended to move the soft palate anteriorly to decrease obstruction of the airway during sleep. The mouthpiece was produced in ten different sizes to accommodate a range of oral dimensions. Subjects with OSA in this single-center, single-night study underwent a polysomnography (PSG) study at baseline, followed by PSG during use of OPT.

resultsFifty-six men and 20 women, aged 50.8 ± 12.0 years (mean ± standard deviation [SD]), had OSA with apnea-hypopnea indices (AHI) greater than five events per hour at baseline. Body weight averaged 98.0 ± 18.2 kg (mean ± SD), body mass index ranged from 22.6 kg/m(2) to 57.9 kg/m(2) and averaged 32.5 ± 5.8 kg/m(2) (mean ± SD). OPT was generally well tolerated without any serious adverse events. Baseline AHI was 38.7 ± 27.5 events/hour (mean ± SD) and was reduced with treatment to 24.6 ± 25.7 events/hour (P < 0.001, Cohen's d 0.53). Treatment produced AHI less than or equal to ten events/hour in 38% of the subjects. Oxygen desaturation index was 30.1 ± 23.7 events/hour at baseline versus 15.8 ± 19.1 events/hour with treatment (P < 0.001, Cohen's d 0.66). The minimum oxygen saturation increased with treatment from 77.9 ± 8.3 to 82.2 ± 7.9 (P < 0.001, Cohen's d 0.53). Stage-N1 sleep shifts, total sleep-stage shifts, and awakenings were significantly reduced with treatment.

conclusionThis single-center, single-night feasibility study demonstrates that OPT can improve OSA in certain subjects identifiable by PSG during systematic usage. In appropriately responsive patients, OPT shows potential as a clinically useful new alternative for treatment of OSA without the need for custom manufacture of an oral device component.
