Migraine and pregnancy-related headaches as a risk factor for cardiovascular and cerebrovascular events in pregnancy: a systematic review and meta-analysis of over 94 million pregnancies.

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 prevalent among women of childbearing age and is associated with increased long-term cardiovascular and cerebrovascular risk. Pregnancy, a hypercoagulable state, may potentiate these risks. This study aimed to quantify the association between migraine or pregnancy-related headaches and cerebrovascular and cardiovascular events during pregnancy and the postpartum period.
methodsWe conducted a PRISMA-compliant systematic review and meta-analysis of observational studies comparing pregnant women with and without migraine or pregnancy-related headaches. PubMed, Scopus, and Web of Science were searched through May 8, 2025. Adjusted odds ratios (ORs) were pooled using random-effects models.
resultsTwelve studies encompassing 94,195,776 pregnancies met the inclusion criteria. Migraine was associated with markedly increased odds of all strokes and transient ischemic attacks (OR 10.45; 95% CI 4.27-25.57) and ischemic stroke (OR 7.14; 95% CI 2.51-20.31). Hemorrhagic stroke risk was elevated but not statistically significant overall (OR 2.25; 95% CI 0.99-5.18), while subarachnoid hemorrhage showed a 69% increased odds. Regarding cardiovascular events: myocardial infarction risk increased by 96%, peripartum cardiomyopathy odds were 2.68-fold (95% CI 1.73-4.14), and spontaneous coronary artery dissection odds were 9.21-fold higher (95% CI 3.72-22.82). All included studies were rated as "good" quality by the Newcastle-Ottawa Scale.
conclusionsMigraine and pregnancy-related headaches are independent risk factors for a broad spectrum of cerebrovascular and cardiovascular events during pregnancy and the puerperium. These findings highlight the need for heightened clinical surveillance, targeted cardiovascular risk counselling, and multidisciplinary management strategies for this population.
