Blood Pressure During Hospital Stay for Delivery and Risk for Postpartum Readmission for Hypertension.
Article in O&G open, 2024. 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 evaluate the association of changes in peripartum blood pressure (BP) with risk for postpartum readmission for hypertension.
methodsWe conducted a retrospective cohort study of birthing individuals delivering from January 1, 2017, to March 1, 2020, in Louisiana. We identified patients with postpartum readmission for hypertension (readmission within 30 days of delivery) and compared BP and clinical and sociodemographic characteristics with those of patients who were not readmitted for hypertension. Patients were also grouped by their BP at both admission for delivery and 36 hours postpartum: systolic below 130 mm Hg and diastolic below 80 mm Hg, systolic 130-139 mm Hg or diastolic 80-89 mm Hg, systolic 140-149 mm Hg or diastolic 90-99 mm Hg, and systolic 150 mm Hg or higher or diastolic 100 mm Hg or higher. Logistic regression was performed to identify risk factors for postpartum readmission for hypertension.
resultsIn our cohort of 17,587 individuals, 329 patients (1.9%) experienced postpartum readmission for hypertension. Increased admission BP (adjusted odds ratio [aOR] 2.26, 95% CI, 1.75-2.928), increased 36-hour postpartum BP (aOR 2.36, 95% CI, 1.58-3.53), and preeclampsia (aOR 2.47, 95% CI, 1.83-3.34) were the strongest predictors of postpartum readmission for hypertension. Black race, anemia, and increased maternal age also significantly increased the odds of postpartum readmission for hypertension (all
conclusionEven mildly elevated BP at delivery admission and persisting postpartum significantly increased risk for postpartum readmission for hypertension.
