Neonatal pre-discharge heart rate variability and neurodevelopmental outcomes at 1- and 5-years in children with transposition of the great arteries.

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
backgroundChildren with congenital heart disease (CHD) are at increased risk for long-term neurodevelopmental impairment, yet reliable pre-discharge biomarkers are lacking. Heart rate variability (HRV), a non-invasive measure of autonomic regulation, has been proposed as a potential predictor.
methodsIn This retrospective cohort study (2015-2024), 58 infants with transposition of the great arteries (TGA) who underwent 24-h Holter electrocardiogram (ECG) before discharge. HRV time domain metrics were calculated by segmented 10 min epochs and summarized and neurodevelopment assessed at 1 year (n = 55) and at 5 years (n = 21). Were analyzed using Pearson correlations and multivariable linear regression adjusting for cardiopulmonary bypass (CPB) time, postnatal age at ECG, socioeconomic status, and hospital stay.
resultsNeonatal HRV was not independently associated with cognitive, language, or motor outcomes at either follow up. Exploratory bivariate analyses showed a weak, non-significant negative correlation between vagally mediated HRV and visual motor integration at 5 years. Longer CPB time and lower socioeconomic status were independent predictors of poorer neurodevelopment.
conclusionNeonatal pre-discharge HRV is not a reliable predictor for neurodevelopment at 1 or 5 years in children with TGA, highlighting the importance of perioperative complexity and socioeconomic factors. Multimodal longitudinal assessments are needed to better understand brain heart interaction in CHD. IMPACT: First study to longitudinally assess associations between neonatal HRV and neurodevelopmental outcomes at 1 and 5 years in children with TGA. Neonatal pre-discharge HRV is not independently associated with later developmental outcomes at 1 and 5 years in children with TGA. Single pre discharge HRV measurements should be interpreted cautiously, longitudinal and multimodal assessments are likely needed to identify neurodevelopmental risk in CHD.
