Altered Topology of Brain Structural Network in Patients With Migraine Without Aura: A Structural MRI Study.
Article in European journal of pain (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMigraine is a neurovascular disease associated with significant morbidity and disability, but its underlying pathophysiology remains elusive. Functional alterations within the brain are frequently observed in individuals with migraine, whereas structural changes are less frequently documented. This study was primarily designed to investigate topological abnormalities in brain structural networks in patients with migraine using structural magnetic resonance imaging.
methodsGraph theoretical analysis was used to compare global and regional topological properties of grey matter structural networks in 37 migraine patients and 44 age-, gender-, and education-matched healthy controls. Structural correlation networks were constructed for both groups on the basis of measurements of grey matter volume.
resultsA statistically significant difference was observed in the scores of Self-rating Anxiety Scales (SAS) and Self-rating Depression Scales (SDS) between migraine patients and healthy controls. The brain networks of patients exhibited significantly increased path length, decreased clustering coefficient, and small-worldness at the global level. At the regional level, brain regions with changes in node degree/betweenness centrality in migraine patients were predominantly located in the left cuneus, the left fusiform gyrus, the left precuneus, the right precentral gyrus, the right middle frontal gyrus, and the bilateral lingual gyrus.
conclusionThe findings of this research indicate that the topological organisation is less efficient in individuals who experience migraine. This may provide new insight into the pathogenesis of migraine from a structural perspective.
trial registrationChinese Clinical Trial Registry, ChiCTR2000033995 SIGNIFICANCE: The present study addresses the central pathogenesis of migraine and shows at a structural level that global brain properties are altered in migraine patients and that regional properties of specific brain regions also show abnormalities. This provides new ideas and an objective basis for the future diagnosis and treatment of migraine.
