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

Existing evidence for brain morphometric changes and functional connectivity alterations in patients with obstructive sleep apnea is mixed. The current study aimed to meta-analyse the neuroimaging data, and thus synthesize a brain map showing locations with morphometric and functional connectivity differences between patients with obstructive sleep apnea and controls. Published studies to 2018 were retrieved and included into the analysis if they reported such between-group differences using voxel-based morphometry or resting-state functional magnetic resonance imaging, and reported the results in the form of brain coordinates based on whole-brain analysis. Twelve voxel-based morphometry and seven resting-state functional magnetic resonance imaging studies that comprised a total of 1,113 participants fulfilled the inclusion criteria. Compared with healthy controls, patients with obstructive sleep apnea had reduced resting-state connectivity in the right anterior cingulate and larger grey matter volume in the right insula. Patients with obstructive sleep apnea do have morphometric and resting-state connectivity alterations in the brain. These neural correlates may help explain the effects of obstructive sleep apnea on the emotion, cognition and quality of life of patients, and may be used in future for evaluating its treatment outcome.
