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

Background: The glymphatic system is a crucial pathway for the clearance of metabolic waste from the brain, and its dysfunction has been linked to various neurodegenerative disorders. This study examined the connection between insomnia and glymphatic system dysfunction, offering a novel perspective on the pathophysiological mechanisms underlying insomnia. Methods: We prospectively recruited 25 patients with insomnia and 37 healthy controls for a case-control study. All participants underwent routine magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) scans. Glymphatic activity was measured via diffusion tensor image analysis along the perivascular space (DTI-ALPS). All patients with insomnia underwent a polysomnogram (PSG) examination and were evaluated using the Pittsburgh Sleep Quality Index (PSQI). We used United Imaging Healthcare artificial intelligence to count the number of enlarged perivascular spaces (ePVSs) in the centrum semiovale, corona radiata, basal ganglia, and hippocampal regions. Results: The left ALPS index, right ALPS index, and average ALPS index were found to be lower in the insomnia group than in the control group [P false discovery rate (P Conclusions: Insomnia is associated with impairments in glymphatic circulation, and the average ALPS index can serve as an imaging biomarker for glymphatic dysfunction in insomnia, aiding in the prevention of further progression to dementia.
