Antenatal Diagnosis of a True Knot of the Umbilical Cord: A Rare Case With a Successful Surgical Outcome.
Article in Cureus, 2025. 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
True knots of the umbilical cord (TKUCs) are rare and can compromise fetal well-being. Their diagnosis is typically made at delivery, with antenatal identification remaining rare. This case report describes an antenatal diagnosis of a TKUC at 35 weeks' gestation in a 28-year-old third gravida with two previous miscarriages. The patient presented with reduced amniotic fluid and absent fetal movements. Ultrasound imaging raised suspicion of a TKUC, prompting an emergency cesarean section. A healthy neonate was delivered. This case highlights the potential role of color Doppler ultrasound and maternal vigilance in identifying TKUCs before delivery. Despite diagnostic challenges, heightened clinical awareness and timely intervention can contribute to favorable perinatal outcomes. Future research should aim to improve diagnostic accuracy and develop effective risk-stratification tools.
