Neurosonographic Evaluation of Cerebral Cortical Development in Fetuses With Congenital Heart Disease: A Systematic Review of the Literature.

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
This systematic review collated data from neurosonography and ultrasound evaluations to assess changes in the cortical development of fetuses with congenital heart disease (CHD). Of the 135 articles identified by two independent reviewers, five that satisfied our inclusion criteria were selected. Cortical evaluation was performed by 2D and/or 3D ultrasound via either a transabdominal or transabdominal plus transvaginal approach. One study used a brain-age evaluation algorithm, while the other four measured the depths of brain fissures. Gestational age at the time of fetal evaluation was very heterogeneous, from 20 to 37 weeks. Four of the studies included several types of CHD but one included only fetuses with tetralogy of Fallot. All five studies detected significant delays in the development of brain sulci and gyri in CHD fetuses compared to controls. In general, the studies were of good methodological quality, but all showed some risk of bias. The main methodological issue was the lack of comparison of ultrasound findings with magnetic resonance imaging data. To conclude, ultrasound was found useful in the evaluation of fetal cortical development, showing that fetuses with CHD present some degree of delayed cortical development, but postnatal studies are needed to understand if it correlates with impaired neurodevelopment.
