Methodological Assessment of ExoGAG for Isolation of Cerebrospinal Fluid Extracellular Vesicles as a Source of Biomarkers.
Article in International journal of molecular sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Extracellular vesicles (EVs) in cerebrospinal fluid (CSF) represent a valuable source of biomarkers for central nervous system (CNS) diseases, offering new pathways for diagnosis and monitoring. However, existing methods for isolating EVs from CSF often prove to be labor-intensive and reliant on specialized equipment, hindering their clinical application. In this study, we present a novel, clinically compatible method for isolating EVs from CSF. We optimized the use of ExoGAG, a commercially available reagent that has been tested in plasma, urine and semen, and compared it directly with differential ultracentrifugation using Western blotting, protein quantification, nanoparticle tracking analysis, and cryogenic electron microscopy. Additionally, we analyzed the presence of specific microRNAs (miRNAs) known to be present in CSF-derived EVs. Our data demonstrate that ExoGAG is an effective method for isolating EVs from CSF, yielding a higher amount of EVs compared to traditional ultracentrifugation methods, and with comparable levels of specific miRNAs. In conclusion, the use of ExoGAG in a clinical setting may facilitate the testing of biomarkers essential for tracking brain pathology in CNS diseases.
