Adverse pregnancy outcomes and long-term risk of stroke: a Swedish nationwide co-sibling study.
Article in European heart journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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 AND
aimsThe lifelong risk of stroke following adverse pregnancy outcomes, and potential causality, are unknown. This study examined five major adverse pregnancy outcomes and long-term risk of stroke in a large population-based cohort.
methodsA national cohort study was conducted of all 2 201 393 women with a singleton delivery in Sweden during 1973-2015, followed up for stroke through 2018. Cox regression was used to determine hazard ratios (HRs) for stroke associated with preterm delivery, small for gestational age, preeclampsia, other hypertensive disorders, and gestational diabetes, adjusting for other maternal factors. Co-sibling analyses assessed for potential confounding by shared familial (genetic or environmental) factors.
resultsIn 48 million person-years of follow-up, 667 774 (30%) women experienced an adverse pregnancy outcome and 35 824 (1.6%) women were diagnosed with stroke. All five adverse pregnancy outcomes were independently associated with long-term increased risks of stroke. With up to 46 years of follow-up, adjusted HRs for stroke associated with specific adverse pregnancy outcomes were: gestational diabetes, 1.86 (95% confidence interval 1.69-2.04); other hypertensive disorders, 1.82 (1.67-1.98); preterm delivery, 1.40 (1.36-1.45); preeclampsia, 1.36 (1.31-1.41); and small for gestational age, 1.26 (1.22-1.29). All HRs remained significantly elevated (1.2- to 2.5-fold) even 30-46 years after delivery. These findings were only partially explained by shared familial factors.
conclusionsIn a large national cohort, women with any of five adverse pregnancy outcomes had increased risks of stroke up to 46 years after delivery. Women with adverse pregnancy outcomes need early preventive actions and long-term follow-up to reduce their lifelong risk of stroke.
