Premature and early menopause and neuroimaging biomarkers of neurodegenerative diseases: a systematic review.
Synthesis in Frontiers in dementia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Premature and early menopause involve ovarian hormone deprivation, which may contribute to later-life vulnerability to cognitive decline and neurodegenerative diseases. Multimodal neuroimaging biomarkers provide a means of detecting structural, microstructural, functional, and molecular brain changes before clinical symptoms emerge. Methods: Following PRISMA guidelines, we conducted a systematic search of PubMed. Study quality was assessed using the Newcastle-Ottawa Scale. Results: Neuroimaging modalities included Conclusion: Converging multimodal neuroimaging evidence suggests that premature and early menopause may be associated with Alzheimer's disease-relevant brain changes. However, findings remain heterogeneous, and longitudinal studies are needed to clarify the temporal relationships between ovarian hormone deprivation and neurodegeneration, and to determine the clinical implication of these findings.
