Impact of umbilical cord length on fetal circulatory system by Doppler assessment.
Observational study in Journal of ultrasound, 2020. 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
introductionNumerous studies have revealed the impact of umbilical cord (UC) length on fetal perfusion; abundant data implicate abnormal UC length to neurological delay and subsequent poor prognoses for fetuses and newborns. Indeed, our group previously developed theoretical approximations that contributed to formulas capable of explaining the impact of UC length on cardiac output.
methodsWe performed an observational study that measured the pulsatility index and flow velocity in umbilical arteries. A special Doppler measured proximal and distal indexes in both arteries. After birth, medical staff measured complete UC length. We obtained maternal and neonatal outcomes from clinical records.
resultsOur study enrolled 20 pregnant mothers. We found that flow velocities in the two edges were different: fetal edges exhibited greater velocity in the majority of cases; but, when we compared pressure differentials (ΔP), the pulsatility index was significantly related to umbilical cord length.
conclusionsFetal perfusion, welfare, and viability are related to UC function as the conveyor of all fetal volemia. Excessive UC length affects cardiac dynamics and increases peripheral vascular resistance. Further studies could validate routine use of the differential proximal and distal measurements proposed in this article, and their implications in in utero fetal heart function. We also hope that early diagnosis or UC alterations could alert neonatologists and obstetricians to clinical conditions of the fetus.
