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

objectiveThis study determined the cord plasma-derived extracellular vesicle (exosomes; 30-160 nm particles) proteomic profile in patients who had spontaneous preterm birth (PTB) or preterm premature rupture of membranes (pPROM), compared to those who delivered at term regardless of labor status.

methodsThis is a cross-sectional analysis of a retrospective cohort that quantified and determined the proteomic cargo content of exosomes present in cord blood plasma samples in PTB or pPROM, and normal term in labor (TL) or term not in labor (TNIL) pregnancies. Exosomes were isolated by differential centrifugation followed by size exclusion chromatography. Exosomes were characterized by nanoparticle tracking analysis (quantity and size) and markers (dot blots for exosome markers). The exosomal proteomic profile was identified by liquid chromatography-mass spectrometry (LC-MS/MS). Ingenuity pathway analysis determined canonical pathways and biofunctions associated with dysregulated proteins.

resultsCord plasma exosomes have similar quantity and exhibit both tetraspanin and ESCRT protein markers specific of exosomes regardless of the conditions. Proteomics analysis exhibited several similar markers as well as very unique markers in exosomes from each condition; however, bioinformatics analysis revealed a generalized and non-specific inflammatory condition represented in exosomes from different condition that is not indicative of any specific underlying biological functions indicative of an underlying pathology.

conclusionsCompared to maternal plasma and amniotic fluid exosomes, the value of cord plasma derived exosomes is limited. Quantity, character, and proteomic cargo contents in exosomes or the pathways and functions represented by differentially expressed proteins do not distinguish specific conditions regarding normal and abnormal parturition. The value of cord plasma exosome proteomic cargo has limited value as an indicator of an underlying physiology or as a biomarker of fetal well-being.
