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

purposeThe purpose of this study was to elucidate the effect of a neck-worn position therapy device (PTD) and oral appliance (OA) on sleep parameters in patients with obstructive sleep apnea (OSA).

methodsPatients with an apnea hypopnea index (AHI) of 5/h or more at baseline polysomnography were divided into a PTD group and an OA group randomly. All participants underwent a type 1 polysomnography for diagnosis and device-set outcome measurements.

resultsThe PTD decreased the AHI from a mean of 24.2/h to 16.7/h, and the OA decreased the AHI from 20.8/h to 10.3/h. Snoring duration decreased from 31.1% to 16.9% in the PTD group, and from 41.2% to 30.7% in the OA group. There were no significant differences in these decreases between the two groups. The PTD decreased sleep-time percentage in the supine position from a mean of 67.4% to 4.5%, despite five patients who were unable to avoid the supine position. There were no significant differences in improvement in sleep efficiency, percentage of stage wake, stage N1, stage N2, and stage REM, and overall arousal and respiratory arousal indices between the two groups. However, the spontaneous arousal index worsened in the OA responders but remained unchanged in the PTD responders. Percentage of stage N3 sleep (%N3) was improved in the PTD responders but not in the OA responders. There were significant differences in spontaneous arousal index and %N3 between the two groups.

conclusionPTDs are a potential treatment modality that does not disturb sleep in patients with OSA.
