Electrocardiographic Characteristics of Healthy Newborns During the First Postnatal Hour.
Article in Journal of cardiovascular development and disease, 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
backgroundFew studies have reported electrocardiogram data collected during the neonatal period. The aim of this study was to evaluate electrocardiographic parameters in healthy neonates during the first postnatal hour.
methodsElectrocardiogram samples taken during the first hour of life from newborns born at our hospital were analyzed in this prospective observational study. Demographic data and possible electrocardiogram changes were studied. The results were statistically analyzed.
resultsA total of 260 patients were included during the study period. Among these, 50% were male (n = 130), the mean gestational age was 38.1 ± 1.4 weeks, and the mean birth weight was 3.2 ± 1.4 kg. In the electrocardiograms obtained, low atrial rhythm was detected in 0.3% of the patients (n = 1). Right axis deviation was observed in 1.5% of the patients (n = 4), and left axis deviation was observed in 1.2% of the patients (n = 3). An abnormal P-axis was found in one patient (0.3%), and an abnormal QRS-T angle was found in one patient (0.3%). No statistically significant differences were observed in the other parameters.
conclusionPhysiologic electrocardiographic findings can be observed during the first postnatal hour. Further studies are needed to clarify the interpretation of the electrocardiogram findings.
