Long-Term Maternal Health Outcomes Following Severe Maternal Morbidity: A 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 the long-term morbidity experienced by women with a history of severe maternal morbidity (SMM).
designProspective population-based cohort study.
settingA tertiary medical centre. POPULATION: All women who experienced SMM between 2013 and 2018 and a matched comparison group without SMM.
methodsSMM was defined as maternal admission to the intensive care unit during the delivery hospitalisation. Women with SMM were matched 1:1 to controls based on mode and year of delivery. Multivariable Cox proportional hazards regression models were used to assess the adjusted risks of long-term diagnoses and hospitalisations, controlling for sociodemographic and clinical characteristics.
main outcome measuresLong-term incidence of morbidities and hospitalisations.
resultsA total of 288 women were included in the study, with a follow-up ranging from 6 to 11 years following the index pregnancy. Compared to women with no SMM in the index pregnancy, the SMM group demonstrated a significantly higher risk of cardiovascular and endocrine morbidities (adjusted HR: 4.01, 95% CI: 2.03-7.90 and 2.17; 95% CI: 1.24-3.79, respectively). Additionally, women with SMM in the index pregnancy had higher rates of SMM-related hospitalisations (adjusted HR: 1.90, 95% CI: 1.10-3.29), all-cause hospitalisations (adjusted HR: 2.21, 95% CI: 1.36-3.58) and hospitalisations within the first year following the index pregnancy (adjusted HR: 4.94, 95% CI: 1.06-23.13).
conclusionsWomen with SMM require vigilant multidisciplinary medical surveillance following discharge from their delivery hospitalisation. The occurrence of SMM may serve as a warning sign of significant long-term health risks.
