Fetal and Obstetric Complications Among Pregnant Women With Congenital Heart Disease in a Georgia Medicaid Dataset.
Article in Birth defects research, 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
backgroundSurvival to reproductive age is common among women with congenital heart disease (CHD). We evaluated fetal and obstetric complications in a population-based cohort of women with CHD enrolled in Georgia (GA) Medicaid.
methodsWe identified 3904 pregnancies (96.0% singleton) among 2267 women with CHD, ages 11-50 (49.2% Black; 76.3% urban), enrolled in GA Medicaid from 2008 to 2019. Diagnoses and outcomes were defined using International Classification of Diseases (ICD) codes. Associations between CHD anatomic group and fetal and obstetric outcomes were assessed using chi-square tests. Multivariate logistic regression models were adjusted for covariates, using isolated coronary anomalies as the reference group.
resultsObstetric complications occurred in 36.2% of pregnancies and did not differ significantly by CHD anatomic group (p = 0.5301). Fetal complications were significantly more common in all CHD groups compared with coronary anomalies, including higher prematurity and fetal growth restriction (FGR) rates (prematurity: p < 0.0001; FGR: p = 0.0238). In multivariate analysis, complex right ventricular outflow tract (RVOT) defects, shunts, univentricular lesions, transposition of the great arteries (TGA), left-sided and right-sided valve lesions were associated with increased odds of fetal complications compared to coronary anomaly CHD [aOR, 95% CI: complex RVOT 4.85, 1.85-12.71; shunt 4.00, 1.56-10.26; univentricular: 3.65, 1.35-9.90; TGA: 3.64, 1.24-10.63; left-sided valve: 3.23, 1.26-8.31; and right-sided valve: 3.11, 1.19-8.12].
conclusionsPregnancies among women with CHD carry increased risk of prematurity and FGR rates across CHD anatomic groups compared with coronary anomalies. Close monitoring for fetal and obstetric complications is warranted regardless of CHD subtype, including those traditionally considered to have lower maternal risk.
