Perinatal outcomes and 2017 ACC/AHA blood pressure categories.
Article in Pregnancy hypertension, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveTo evaluate the association of blood pressure category < 20 weeks according to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) criteria with adverse perinatal outcomes. STUDY
designA retrospective cohort study of singleton deliveries between 1/2014 and 10/2017 was undertaken. Blood pressure category assigned by 2017 ACC/AHA criteria applied to blood pressures prior to 20 weeks gestation: normal (systolic < 120 and diastolic < 80), elevated blood pressure (systolic 120-129 and diastolic < 80 mmHg), stage 1 hypertension (systolic 130-139 and/or diastolic 80-89), stage 2 hypertension (prior diagnosis of chronic hypertension or systolic ≥ 140 or diastolic ≥ 90 mmHg).
main outcome measuresThe primary outcome was preeclampsia. Secondary outcomes included preterm birth and postpartum readmission. Chi-square, ANOVA and Kruskal-Wallis tests and multivariable Poisson regression were used for analysis.
resultsOf the 6,067 eligible pregnancies, 3,855 (63.5%) had normotensive blood pressure, 1,224 (20.2%) elevated blood pressure, 624 (10.3%) stage 1 hypertension, and 364 (6.0%) stage 2 hypertension. Compared to 4.6% prevalence of preeclampsia among normotensive pregnancies, higher categories were associated with higher preeclampsia prevalence: elevated blood pressure (10.7%, adjusted relative risk (aRR) 2.2, 95% confidence interval (CI) 1.8-2.6), stage 1 hypertension (15.1%, aRR 2.7, 95% CI 2.2-3.4) and stage 2 hypertension (38.7%, aRR 6.2, 95% CI 5.1-7.4). Non-normal categories were also associated with a higher risk of preterm birth and postpartum readmission.
conclusionPatients with elevated blood pressure and stage 1 and 2 hypertension at < 20 weeks are at increased risk of adverse obstetric perinatal outcomes.
