Ultrasound blood flow characteristics changes in fetal umbilical artery thrombosis: A retrospective analysis.
Article in World journal of clinical cases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundUmbilical artery thrombosis (UAT) is extremely uncommon and leads to adverse perinatal outcomes. Hypercoagulation of blood in pregnant women is suspected to be an important risk for UAT. Ultrasound is an effective way to detect thrombosis. The mother can monitor her own fetal health using ultrasound, which enables her to take preventative action in case of emergency.
aimTo investigate ultrasonic blood signal after UAT in the umbilical artery, and evaluate the relationship between hypercoagulability and UAT.
methodsWe described a case of a newly formed UAT with markedly altered ultrasonic indices of umbilical artery blood flow, and retrospectively studied it with 18 UAT patients confirmed by histopathology from October 2019 and March 2023 in Xiamen Women and Children's Hospital. Patients' information was collected from medical archives, including maternal clinical data, neonatal outcomes, pathological findings and ultrasonic indices of umbilical artery blood flow, such as systolic-diastolic duration ratio (S/D), resistance index (RI), pulsatility index (PI) and peak systolic velocity (PSV). Ultrasound and coagulation indices were analyzed with matched samples
resultsA patient with normal findings in second and third-trimester routine ultrasound scan developed UAT with severe changes in ultrasonic indices of umbilical artery blood flow (within 2.5
conclusionSignificant changes in ultrasound indicators after UAT were demonstrated. PSV can play important roles in the diagnosis of UAT. Hypercoagulability alone is not sufficient for the occurrence of UAT.
