Insights Into Congenital Lymphatic Anomalies Underlying Fetal Effusions.

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
objectiveWe describe a series of pregnancies with autosomal dominant lymphedema and generalized lymphatic dysplasia in the fetus diagnosed with prenatal exome or genome sequencing. We focus on specific syndromes, fetal features, and parental symptoms to deepen our understanding of congenital lymphatic anomalies.
methodsPregnancies with one or more fetal effusions were prospectively enrolled from 2017 to 2024 and underwent exome or genome sequencing. Fetal effusions included increased nuchal translucency ≥ 3.5 mm, cystic hygroma, pleural effusion, pericardial effusion, ascites, and/or skin edema. Records were reviewed to extract personal and family history, ultrasound findings, and pregnancy outcomes.
resultsAmong 303 pregnancies with one or more fetal effusions, eight (3%) had a molecular diagnosis of autosomal dominant lymphedema or generalized lymphatic dysplasia. Gestational age at detection of fetal effusion(s) ranged from the first through third trimesters. Four fetuses inherited the genetic variant(s) from a biological parent. Of these, one parent was asymptomatic, and three had largely milder symptoms than their fetus. Perinatal outcomes were more favorable for fetuses with heterozygous PIEZO1 variants.
conclusionAutosomal dominant lymphedema and generalized lymphatic dysplasia can present with a breadth of fetal effusions from the first through third trimesters and are frequently inherited from a biological parent with less severe symptoms. These data provide a deeper understanding of how congenital lymphatic anomalies manifest in utero and inform expectations about recurrence risk in future pregnancies.
