Agenesis of the Ductus Venosus and Its Association With Genetic Abnormalities.
Article in Prenatal diagnosis, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo investigate the association of agenesis of the ductus venosus (ADV) with genetic abnormalities using genetic studies-Chromosomal Microarray Analysis (CMA) and Exome Sequencing (ES).
designRetrospective study of all fetuses diagnosed with ADV between January 2013 and December 2022 in a tertiary center.
resultsADV was diagnosed in 33 fetuses. The diagnosis was made at a mean gestational age of 21.2 ± 8.4 weeks. Conventional karyotype was applied in a single fetus (3.0%), CMA was applied in 21 fetuses (66.7%), and five fetuses (22.8%) were additionally tested with ES. ADV was isolated in eight fetuses (24%), whereas in 25 (76%) it was associated with abnormal ultrasound findings, including increased nuchal translucency (NT), intrauterine growth restriction (IUGR) and variable structural malformations, mostly cardiac (42%) followed by central nervous system (CNS) and skeletal malformations (24%). Genetic abnormalities were found in six fetuses out of 22 investigated (27%), of which 3 were detected by ES, 3 by CMA and 1 by conventional karyotype. A higher incidence of genetic aberrations was evident among ADVs associated with abnormal ultrasound findings. Genetic abnormalities were indicative of Prader Willi/Angelman syndrome, Noonan syndrome, CASK related disorder, 16q24.3 microdeletion syndrome and Trisomy 21.
conclusionADV associated with abnormal ultrasound findings is commonly correlated with genetic abnormalities and consequently unfavorable pregnancy outcomes. Our study emphasizes the value of genetic studies chiefly among cases associated with abnormal ultrasound findings, enabling early diagnosis of fetal pathologies associated with ADV, and providing better parental counseling.
