Predictive Value of Venous Ductus Doppler in Perinatal Outcomes in Fetal Growth Restriction.
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
Introduction Fetal growth restriction (FGR) is associated with perinatal morbidity, acidosis, and adverse neurological outcomes. While arterial Doppler of the umbilical artery (UA) and middle cerebral artery informs surveillance, ductus venosus (DV) Doppler may better reflect central hemodynamics and impending cardiac decompensation. This study evaluated the predictive value and clinical significance of DV Doppler velocimetry for acid-base status, early postnatal Apgar score (AS), neonatal morbidity, and neurological outcomes in infancy. Methods In a retrospective, single-center cohort, pregnancies with and without FGR underwent UA and DV Doppler assessment. DV waveforms were classified as normal or pathological based on the presence of an absent or a reversed A-wave. Neonatal outcomes included umbilical artery blood pH, AS at standard early postnatal intervals, composite neonatal morbidity, and neurological status during the early neonatal period and later infancy. Associations were examined using Fisher's exact tests, and diagnostic performance was summarized with sensitivity, specificity, positive predictive value, and negative predictive value. Results A pathological DV was recorded in 15.4% of fetuses with FGR. In this subgroup, acidosis (pH <7.20) occurred in 100% of cases and was significantly less frequent among fetuses with normal DV findings (p <0.001). At one minute, a low AS (0-3) was present in 75% of newborns with pathological DV, and at five minutes in 25%; all newborns with pathological DV had an AS of ≤7 at both time points, whereas an AS of ≥7 predominated in the normal DV group (p <0.01). Neonatal morbidity was present in 100% of newborns with pathological DV compared with 29.5% in the normal DV group (p <0.001). During the first month, all newborns with pathological DV demonstrated neurological injury on early assessment. Conclusion DV Doppler adds clinically actionable information to arterial Doppler in FGR by identifying venous decompensation at a stage when intervention may alter outcome. Incorporating DV evaluation into routine surveillance can trigger timely delivery when venous compromise is present and support expectant management when venous flow remains normal, helping clinicians balance the risks of prematurity against progressive hypoxic-ischemic injury and may inform perinatal care pathways.
