Polygenic Risk for Pre-Eclampsia and the Long-Term Risk of Incident Hypertension and Cardiovascular Disease: A Population-Based Cohort Study.
Article in BJOG : an international journal of obstetrics and gynaecology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate whether genetic predisposition to pre-eclampsia (PE), measured by a polygenic risk score (PRS), is associated with incident hypertension and cardiovascular disease (CVD) after delivery in Asian women.
designProspective population-based cohort study.
settingData were utilised from the Korean Genome and Epidemiology Study and additional multicentre cohorts. POPULATION: 35 872 parous Korean women aged 40-80 years at last surveillance, with genotype data, no history of hypertension or CVD before delivery, and complete clinical information. For external validation, 559 parous Korean women were included.
methodsThe PE-PRS was calculated for Asian women, and the study population was divided into the high PE-PRS and low PE-PRS groups. The long-term risks of incident hypertension and CVD (ischaemic heart disease or stroke) after delivery were compared between the groups.
main outcome measuresIncident hypertension and CVD after delivery.
resultsWomen in the high PE-PRS group had an increased risk of developing hypertension (adjusted hazard ratio [aHR] 1.25, 95% CI 1.17-1.34) and ischaemic heart disease (aHR 1.28, 95% CI 1.07-1.54) compared to the low PE-PRS group. The risk of hypertension was highest among women with both a history of PE and a high PE-PRS.
conclusionsGenetic predisposition to PE, as measured by the PE-PRS, is associated with an elevated risk of incident hypertension and ischaemic heart disease in Asian women. These findings suggest the potential utility of the PE-PRS as a complementary tool in assessing individualised hypertension risk in parous women.
