Coagulation Factors and White Matter Hyperintensities in Middle-Aged Women With and Without Migraine and Ischemic Stroke.
Article in European journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundMigraine increases the risk of ischemic stroke and white matter hyperintensities (WMH), especially in women. Underlying shared mechanisms may include endothelial activation and hypercoagulability. We assessed these markers in middle-aged women with and without migraine and ischemic stroke to explore their role in WMH development.
methodsWe cross-sectionally measured fibrinogen and von Willebrand factor antigen (VWF:Ag) levels as markers of endothelial activation, and factor (F)IX and FXI activity (FXI:C) as markers of hypercoagulability in four groups of women aged 40-60 years with (1)ischemic stroke, (2)migraine, (3)both ischemic stroke and migraine, and (4)no stroke or migraine. Multivariable linear regression estimated mean differences in coagulation factor levels between groups 1 and 3, with group 4 as the reference.
resultsAmong 166 women (mean age:51 years), (1) 45 had ischemic stroke, (2) 38 had migraine, (3) 48 had both, and (4) 35 had no stroke or migraine. Mean fibrinogen, FIX, and FXI:C levels were similar in all groups compared with group 4. VWF:Ag levels were higher in the ischemic stroke with migraine group (170 [57]%; adjusted β = 31%; 95% CI = 6%-56%) compared with group 4, but not in the other groups. There was no association between coagulation factors and WMH volume in any group.
conclusionsIn women with both stroke and migraine, VWF:Ag levels were increased, while fibrinogen, FIX, and FXI:C were not. This suggests that endothelial activation might be more relevant than a procoagulant state alone in the pathophysiology of ischemic stroke in women with migraine. Coagulation factors did not seem to be related to WMH volume, suggesting other mechanisms may be involved in their development.
