Single-Multiple and Recurrent Pregnancy-Related Complications and Incident Cardiovascular Disease: A Nationwide Data Linkage Study in Wales, UK.
Article in Journal of the American Heart Association, 2026. 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
backgroundPregnancy-related complications are linked to increased cardiovascular disease risk, but comprehensive evaluations of diverse complications, particularly multiple or recurrent events, are limited.
methodsA national retrospective cohort study was conducted using the Secure Anonymised Information Linkage (SAIL) Databank in Wales. Exposures were hypertensive disorders of pregnancy, gestational diabetes, placental abruption, stillbirth, small for gestational age, fetal growth restriction, and preterm birth. Multiple complications were defined as >1 complication in the first pregnancy, and recurrent complications as the same complication in both the first and second pregnancies. Outcomes were incident ischemic heart disease, stroke, heart failure, and atrial fibrillation. Cox regression estimated hazard ratios (HRs).
resultsA total of 298 515 women (mean age 27.2 years; SD 6.1) were included. Multiple pregnancy-related complications were associated with increased risk of ischemic heart disease (hazard ratio HR, 2.88 [95% CI, 2.27-3.67]), stroke (HR, 2.03 [95% CI, 1.55-2.65]), heart failure (HR, 3.18 [95% CI, 2.34-4.32]), and atrial fibrillation (HR, 1.80 [95% CI, 1.20-2.72]) compared with no complications. A dose-response relationship was observed, with progressively higher cardiovascular disease risk for multiple compared with single complications and elevated risk for both groups relative to women without complications. Recurrent pregnancy-related complications increased the risk of ischemic heart disease (HR, 1.93 [95% CI, 1.26-2.95]), stroke (HR, 1.89 [95% CI, 1.25-2.85]), heart failure (HR, 3.61 [95% CI, 2.32-5.60]), and atrial fibrillation (HR, 2.45 [95% CI, 1.38-4.37]) compared with no complication.
conclusionsWomen experiencing pregnancy-related complications encounter higher risks of cardiovascular disease, especially with multiple or recurrent complications. Comprehensive cardiovascular risks assessment and targeted prevention should be prioritized for this group.
