Maternal and fetal outcomes in patients with congenital heart disease associated with pulmonary arterial hypertension in high-altitude areas: a retrospective cohort study.
Article in BMC pregnancy and childbirth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesPulmonary arterial hypertension associated with congenital heart disease (CHD-PAH) increases maternal and fetal risk. This study aimed to analyze maternal and fetal outcomes in patients with CHD-PAH in high-altitude areas.
methodsThe pregnant women with CHD were analyzed retrospectively from 2012 to 2022. Pulmonary artery systolic pressure (PASP) was estimated by echocardiography. Patients were categorized into four groups: no PAH (PASP < 40 mmHg), mild (40 mmHg≤PASP < 50 mmHg), moderate (50 mmHg≤PASP < 70 mmHg) and severe PAH (PASP ≥ 70 mmHg).
results429 pregnant women were included in this study, 187 with no PAH, 102 with mild PAH, 79 with moderate PAH, 61 with severe PAH. The severe PAH group had the highest proportions of NYHA functional classes III/IV, SpO
conclusionsThe level of PASP, NT-proBNP, and NYHA function class, BMI may be useful in risk stratification in pregnancy with CHD-PAH in high-altitude areas.
