Outcomes of Postpartum Preeclampsia: A Retrospective Cohort Study of 1.3 Million Pregnancies.
Article in BJOG : an international journal of obstetrics and gynaecology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectiveWe assessed the association between postpartum preeclampsia and the risk of adverse maternal and neonatal outcomes. Evidence suggests that postpartum preeclampsia is initiated antenatally, but the impact on birth outcomes is unclear.
designRetrospective cohort study.
settingAll deliveries in hospitals of Quebec, Canada. POPULATION: 1 317 181 pregnancies between 2006 and 2022.
methodsWe identified patients who developed preeclampsia in the postpartum period. Using log-binomial regression models, we estimated adjusted risk ratios (RR) and 95% confidence intervals (CI) for the association of postpartum or antepartum preeclampsia with adverse pregnancy outcomes relative to no preeclampsia.
main outcome measuresPreterm birth, placental abruption, severe maternal morbidity and recurrent preeclampsia.
resultsPostpartum preeclampsia was less frequent than antepartum preeclampsia (n = 4123 [0.3%] vs. 51 269 [3.9%]). Postpartum preeclampsia was associated with preterm birth (RR 1.45, 95% CI 1.34-1.57), placental abruption (RR 1.36, 95% CI 1.16-1.59) and severe maternal morbidity (RR 6.48, 95% CI 5.87-7.16) compared with no preeclampsia. Antepartum preeclampsia was also associated with these outcomes. Moreover, patients with postpartum preeclampsia in a first pregnancy were at risk of adverse outcomes in a subsequent pregnancy, particularly recurrent preeclampsia (RR 7.77, 95% CI 6.54-9.23).
conclusionsPostpartum preeclampsia is associated with adverse outcomes at delivery, despite being detected only postnatally. Our findings suggest that patients with adverse birth outcomes may benefit from blood pressure measurements up to 6 weeks following delivery.
