Reference ranges of left ventricular diastolic multimodal ultrasound parameters in stable preterm infants in the early and late neonatal intensive care admission period.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundDiastolic dysfunction often precedes systolic dysfunction and provides opportunity for management strategies. We aim to present reference ranges for diastolic function parameters in stable preterm infants at 2 timepoints.
methodsUltrasound scans of clinically stable preterm infants < 30 weeks gestation with no antenatal or postnatal complications were analysed for left heart size, mitral blood flows, myocardial velocities and shortening during the early (3 to 21 days) and late (corrected gestation 34 to 37 weeks) neonatal period.
results92 early scans and 64 late scans were included. Mitral blood flow and myocardial velocities increased with augmented atrial function leading to higher EA and e'a' ratios and with relatively high Ee' ratio.
conclusionWe present reference values for many left ventricular multimodal diastolic ultrasound parameters in preterm infants with uncomplicated fetal and neonatal development to guide prospective studies that explore diastolic function and diastolic heart failure in preterm infants.
