Middle Cerebral Artery Peak Systolic Velocity in Fetuses With Transposition of the Great Arteries.
Article in Prenatal diagnosis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo examine peak systolic velocity in the middle cerebral artery (MCA-PSV) in fetuses with transposition of the great arteries (TGA) and evaluate if TGA is associated with fetal anemia.
methodA retrospective, exploratory study with inclusion of singleton fetuses born with TGA at Copenhagen University Hospital Rigshospitalet 2016-2023. Data on MCA-PSV, neonatal hemoglobin and specific diagnoses were manually retrieved from patient files.
resultsIn 52 cases, 205 MCA-PSV measurements from GA 20 + 0 to 39 + 1 met the inclusion criteria. Overall median MCA-PSV MoM was 1.09 (IQR 0.96; 1.20), increasing from 0.97 (IQR 0.86; 1.15) at gestational week 20 + 0 to 24 + 6 to 1.13 (IQR 0.95; 1.19) at gestational week 35 + 0 to 39 + 1. There were no differences in MCA-PSV MoM between cases with and without surgical closure of a VSD. Median hemoglobin concentration was 16.4 g/dL (IQR 15.3-17.2 g/dL) and MCA-PSV was inversely correlated with hemoglobin (-4.81 [95% confidence interval -7.21; -2.41]).
conclusionThe study adds to the limited evidence on MCA-PSV in TGA fetuses, supporting a trend of increasing MCA-PSV MoM with gestational age, although not significant after accounting for multiple measurements. Higher MCA-PSV MoM correlated with lower neonatal hemoglobin. However, findings do not show that TGA fetuses have elevated MCA-PSV due to anemia or that VSD influences MCA-PSV levels.
