1 · What the graph read from it

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.

2 · The registry

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

backgroundWhile cardiopulmonary transition in neonates is well described, molecular changes which accompany it are not. The Extracellular Vesicles in Early preterm neonates and Thrombin generation (EVENT) study sought to explore molecular transition in preterm birth. How this differs from term-born neonates is not well described.

methodsA post hoc evaluation of proteomic data generated from a subset of the prospective, single site observational EVENT study was performed comparing extracellular vesicle enriched plasma from term neonates (n=10) with preterm neonates (n=20) using a mass spectrometry, data dependent acquisition-based proteomic approach. Bioinformatics was performed using MaxQuant proteomics software and R statistical software.

resultsSubstantial differences were found between the preterm and term extracellular vesicle proteome, with proteins involved in extracellular matrix biology, immune function and embryogenesis all differentially expressed. Preterm neonates could be identified by their proteomic profile alone, reflecting their distinct physiology.

conclusionsThese protein expression differences may underlie the pathogenesis of complications of prematurity, such as bronchopulmonary dysplasia, retinopathy of prematurity and intraventricular haemorrhage.
