Clinical Outcomes of the Prospective Pakistan Registry of Echocardiographic Screening in Asymptomatic Pregnant Women.
Article in JACC. Advances, 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
backgroundCardiovascular disease is increasingly recognized as a leading nonobstetric cause of maternal morbidity and mortality worldwide, including low- and middle-income countries.
objectivesThis study evaluated fetomaternal outcomes in women with and without structural heart disease (SHD).
methodsFrom a total of 25,000 patients enrolled in the Prospective Pakistan Registry of Echocardiographic Screening in Asymptomatic Pregnant Women registry between February 2023 and April 2025, 489 pregnancies with SHD were identified and compared with 510 pregnancies without SHD. Adverse fetomaternal outcomes were evaluated in both groups as a composite endpoint, comprising fetal outcomes (preterm delivery, fetal death, or low birth weight) and maternal outcomes (maternal death and pulmonary edema).
resultsThe SHD cohort had a higher mean maternal age (27.3 ± 5.7 vs 26.1 ± 5.2 years; P = 0.011) compared to the non-SHD cohort. Composite adverse maternal outcomes (3.7% vs 0.4%; P < 0.001), fetal outcomes (29.9% vs 13.3%; P < 0.001), and overall fetomaternal outcomes (30.7% vs 13.3%; P < 0.001) were significantly higher in the SHD compared to the non-SHD cohort. SHD was independently associated with adverse fetomaternal outcomes (adjusted OR: 2.67; 95% CI: 1.93-3.70; P < 0.001).
conclusionsProspective Pakistan Registry of Echocardiographic Screening in Asymptomatic Pregnant Women is the first global study linking subclinical echocardiographic abnormalities in asymptomatic pregnant women to adverse fetomaternal outcomes. In a large cohort of asymptomatic pregnant women, an abnormal echocardiogram was found to be associated with 2- to 4 time as many adverse fetomaternal outcomes compared to a normal echocardiogram. Future studies are needed to evaluate optimal timing of screening, cost-effectiveness, and applicability of broad antenatal screening in higher-income countries.
