Management of fetal umbilical vein varix: a survey-based analysis of current clinical practice.
Article in Archives of gynecology and obstetrics, 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
objectiveTo evaluate current diagnostic criteria, risk stratification, and management practices for fetal intra-abdominal umbilical vein varix (FIUVV) among maternal-fetal medicine and obstetric ultrasound specialists in Israel.
methodsA national web-based survey was distributed to specialists, collecting data on diagnostic parameters, classification of severity, surveillance protocols, and delivery timing recommendations. Responses were analyzed descriptively.
results45 specialists (85% response) from 18 centers participated. Diagnosis was most commonly based on FIUVV diameter, with 9 mm the most frequent cutoff, though substantial variation in criteria existed. Severity assessment relied mainly on vessel diameter, flow abnormalities, and thrombus presence. Most respondents recommended detailed anatomical survey and fetal echocardiography. Surveillance and delivery timing recommendations were tailored to risk level, with earlier induction and increased surveillance favored in high-risk cases. However, considerable variability existed among respondents regarding both the frequency of monitoring and the timing of delivery.
conclusionsConsiderable heterogeneity exists in FIUVV diagnosis and management in Israel. Consensus definitions and standardized protocols are needed to improve clinical care and enable comparative research.
