Chronic Sleep Fragmentation Differentially Affects Alzheimer's Disease Pathology in Male and Female APP
Article in Journal of inflammation research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
Introduction: Sleep fragmentation often precedes Alzheimer's disease (AD) diagnosis and represents a potential modifiable risk factor, especially among women who have higher prevalence of both sleep disorders and AD. Methods: This study investigated how chronic sleep fragmentation affects neuroinflammation and amyloid-beta (Aβ) accumulation in male and female APP Results: Sleep fragmentation effectively disrupted sleep patterns in both sexes, reducing light-phase sleep and increasing intradaily variability. Sleep fragmentation increased GFAP immunoreactivity in both sexes, with larger effects in females than males. Surprisingly, sleep fragmentation decreased expression of the microglial activation markers MHCII and Dectin-1 in males. Pro-inflammatory cytokines (IL-1β, CCL2, CXCL2) were significantly elevated following sleep fragmentation, with distinct regional and sex-specific patterns. In females, sleep fragmentation increased PBS-soluble and formic acid-soluble Aβ in the neocortex and medium-sized plaque density in the hippocampus, while males showed decreased detergent-soluble Aβ in the neocortex following sleep fragmentation. Discussion: Chronic sleep fragmentation exacerbates AD-related pathology in APP
