Detection of extracardiac abnormalities by early comprehensive abdominal ultrasound screening in neonates with congenital heart disease.
Observational study in European journal of pediatrics, 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
Congenital heart disease (CHD) is frequently associated with extracardiac abnormalities that can significantly affect prognosis and management. Although abdominal ultrasound is a readily available and noninvasive tool, detailed observational studies on comprehensive screening for neonates with CHD remain lacking. We aimed to evaluate the prevalence of significant abdominal abnormalities detected during early comprehensive ultrasound screening in neonates with CHD. This single-center, retrospective case series included neonates admitted to a tertiary neonatal intensive care unit (NICU) between April 2021 and May 2024 who underwent screening within 14 days of birth. We compared the proportion of neonates with significant abnormalities and the number of abnormalities per patient between those with and without chromosomal abnormalities or malformation syndromes. Among 59 neonates, significant abnormalities were identified in 29 (49.2%). The most common were hydronephrosis (13.6%), hepatomegaly (10.2%), and intestinal malrotation (8.5%). The proportion of significant abnormalities did not differ significantly between the groups with and without chromosomal abnormalities or malformation syndromes (66.7% vs. 39.5%, P = 0.06). However, the number of abnormalities per patient was significantly higher in the former group (1.38 vs. 0.61, P = 0.03).
conclusionEarly comprehensive abdominal ultrasound screening in hospitalized neonates with CHD revealed significant abnormalities in 49.2% of cases. This screening may improve systemic management of patients with CHD, including perioperative care, and facilitate individualized treatment of CHD‒with or without chromosomal or malformation syndromes‒by enhancing phenotype characterization. WHAT IS KNOWN: ・Congenital heart disease (CHD) is frequently associated with extracardiac abnormalities that can affect prognosis and management. ・Detailed observational studies on comprehensive abdominal ultrasound screening for neonates with CHD remain lacking. WHAT IS NEW: ・Early comprehensive abdominal ultrasound screening in hospitalized neonates with CHD revealed significant abnormalities in 49.2%. ・While abnormalities were more frequent in neonates with chromosomal or malformation syndromes, 39.5% of non-syndromic neonates had significant abnormalities; the screening improves systemic management and individualized treatment.
