Long-Term Cardiovascular Impact of Postpartum Treatment After Hypertensive Disorders of Pregnancy: 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 assess whether early antihypertensive treatment after Hypertensive Disorders of Pregnancy (HDP) influences subsequent development of cardiovascular complications. DESIGN AND
settingPopulation-based nationwide cohort of health data set in France. POPULATION: 108 906 women with HDP (excluding pre-existing Chronic Hypertension (CH)) who delivered between 2010 and 2014, with 35 878 (33%) receiving at least one antihypertensive treatment in the month after giving birth.
methodsTraditional Cox model, estimated 10-year cardiovascular risk. Extended Cox Step Function model and Restricted Mean Survival Time evaluated time trends.
main outcome measuresNew-onset CH, heart failure, coronary, cerebrovascular, peripheral artery diseases and 2 composite events (one including CH, the other excluding it) over 10 years following giving birth.
resultsWomen receiving early postnatal antihypertensive treatment had a higher long-term risk of complications over 10 years than non-treated women (CH: aHR = 3.067, 95% CI [2.996-3.139]; composite event including CH: aHR = 3.025 [2.956-3.096]; composite event excluding CH: aHR = 1.451 [1.305-1.614]). Treated women had events earlier than non-treated women, presenting a higher risk at the beginning of the postpartum period. The 10-year absolute risk for CH remained high in both groups: 44% for treated women and 18% for non-treated women.
conclusionOur study shows that women receiving early postpartum antihypertensive treatment are at higher long-term cardiovascular risk, with 44% of them having CH within 10 years. Besides, approximately 1 in 5 women non-treated in the postpartum period subsequently developed CH, demonstrating that many high-risk women are not being identified in the peripartum period and may be missing opportunities for timely intervention.
