Early Maturation of Heart Rate Variability in Very Preterm Infants Depends on Neonatal Factors and Is Associated With Neurodevelopmental Risk.
Article in Acta paediatrica (Oslo, Norway : 1992), 2026. 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
aimThis study investigated central autonomic network maturation deviations using a previously defined machine learning model set to estimate a functional maturation age (FMA) from heart rate variability (HRV) analysis. We investigated whether these deviations were associated with maternal, fetal, perinatal, or postnatal complications and with neurodevelopment at 2 years of age.
methodsDifferences (ΔHRV) between post-menstrual age (PMA) and FMA were measured in a multicenter prospective cohort of 132 preterm infants born < 30 weeks gestational age (GA). The relationship between ΔHRV and clinical factors, occurrence of complications or alterations in neurodevelopment assessed by Ages and Stages Questionnaire (ASQ) at 2 years of age was studied.
resultsΔHRV expressed in weeks delay at 34 weeks of PMA was greater when GA was lower (3 IQR 2.3-3.9) at 24-26 versus 1.3 (IQR 0.8-2.4) at 28-30 weeks GA (p < 0.0001), in cases of bronchopulmonary dysplasia (p < 0.0001) or patent ductus arteriosus (p < 0.0001). ΔHRV was also associated with altered social skills at 2 years of age (OR 2.05, 95% CI 1.02; 4.14 for each week, p < 0.05) but not with ASQ total score (p = 0.06).
conclusionΔHRV, early and non-invasively estimated, depends on GA, perinatal and postnatal complications. Its assessment could contribute to evaluation of neurodevelopmental risk.
