Influence of head position on obstructive sleep apnea severity.
Trial report in Sleep & breathing = Schlaf & Atmung, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
objectiveSupine body orientation plays an important role in precipitating upper airway collapse in a significant proportion of obstructive sleep apnea (OSA) patients known to have supine-predominant OSA (OSAsup). Traditionally, trunk position is used to assess OSAsup, but the role of the head position has not been established. We hypothesized that head position influences OSA independently of trunk position.
methodsHead and trunk positions were determined from subjects undergoing overnight polysomnography. The apnea-hypopnea index (AHI), rapid eye movement (REM), and non-REM sleep time of all trunk and head positions (lateral and supine) were calculated and compared against the complete supine position, i.e., head and trunk supine.
resultsIn 26 subjects, lateral rotation of the head to the right or left with the trunk supine resulted in a significant reduction in AHI from 36.0 ± 22.5 to 25.8 ± 16.6 (p = 0.008), and an AHI drop <10 in 27% of patients. The "trunk lateral-head lateral" position resulted in a more dramatic reduction in AHI from 31.6 ± 20.2 to 4.1 ± 4.1 (p < 0.0001). The distributions of REM and non-REM sleep were not different among positions. In the subgroup with a body mass index (BMI) <32 kg/m
conclusionOSA severity with the trunk in the supine position decreased significantly when the head rotated from supine to lateral, particularly in non-obese patients. These results demonstrate an important influence of head position on the AHI, independently of trunk position and sleep stage, in patients with OSA.
