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

There is growing interest in the role of extracellular vesicles (EVs) in neonatal pathology. This study aimed to characterise circulating EVs following preterm birth. This single-centre prospective observational study included cord and postnatal plasma from preterm (n = 101) and full-term infants (n = 66). EVs were analysed using nanoparticle tracking analysis, flow cytometry, proteomics and procoagulant activity assay. We found changes in the concentration, size, cellular origin and proteomic content of circulating EVs in preterm infants during perinatal adaptation. To understand if these changes were related to prematurity or normal adaptation to extrauterine life, they were also investigated in term infants. There was a dramatic increase in the concentration of small and large EVs on Day 3 in the preterm group; specific subsets of platelet (CD42b
