Prevalence and factors associated with adverse birth outcomes among women with chronic hypertension in Rangpur: A multi-center cross-sectional study.
Article in PloS one, 2025. 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
backgroundHypertension affects approximately 3-5% of pregnancies globally, with an increased risk of adverse birth outcomes (ABOs) among mothers with chronic hypertension, which poses a significant public health challenge. Despite global evidence, there is a lack of studies in Bangladesh specifically investigating the impact of chronic hypertension on birth outcomes. Therefore, the study aims to find the prevalence and factors associated with adverse birth outcomes among women with chronic hypertension who delivered in health facilities.
methodsAn institution-based multi-center cross-sectional study was conducted in 3 different maternity and child hospitals in Rangpur City between June 2023 and September 2023 and recruited 342 hypertensive females who gave birth in an institutional setting within the last 6 months. The outcome variable was the adverse birth outcomes. For the statistical analysis, STATA version 17.0 was used. Descriptive analysis, Pearson's chi-square test, and both the bivariable and multivariable binary logistic regression analyses were conducted to determine the association between birth outcomes and covariates.
resultThe overall prevalence of adverse birth outcomes among the study participants was 36% (95% CI: 30.87, 41.30). Among the study participants, mothers belonging to a family with higher income (AOR: 3.09; 95% CI: 1.51, 6.30), participants with complicated pregnancies (AOR: 2.55; 95% CI: 1.55, 4.21), mothers who had at least one danger sign present in their last pregnancy (AOR: 2.21; 95% CI: 1.17, 4.15), exposure to secondhand smoke during their pregnancy (AOR: 3.33; 95% CI: 1.16, 9.60) were significantly associated with adverse birth outcomes among hypertensive pregnant women.
conclusionThis study observed a high prevalence of adverse birth outcomes among pregnant women with chronic hypertension who had an institutional delivery. The finding warrants immediate community-based action focused on the important factors to reduce adverse birth outcomes among hypertensive mothers. Further longitudinal studies are needed to identify any causal association between important variables and adverse birth outcomes.
