Enhanced Separation of Extracellular Vesicles Using Capillary Isotachophoresis With Spacer Compounds.
Article in Electrophoresis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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) are pivotal in numerous physiological and pathological processes, such as immune responses, viral pathogenesis, pregnancy, cardiovascular diseases, and cancer progression. Their capacity to influence complex intracellular pathways highlights their therapeutic potential in addressing various conditions, including neurodegenerative diseases and cancer. A novel capillary isotachophoresis (cITP) method was developed for the electrokinetic characterization of pre-isolated EVs. Distinct peaks could be resolved at near-baseline resolution using a novel mixture of spacer ions and laser-induced fluorescence (LIF) detection. The vesicles were effectively separated from the unbound carboxyfluorescein diacetate succinimidyl ester (CFDA-SE) amine-reactive fluorescent stain used to detect them and from residual contaminants. The identity of the peaks shown in the electropherograms was validated via various methods, including incubation with specific antibodies or spiking of putative contaminants, such as proteins and lipoproteins. This report thus provides a detailed proof-of-concept for using cITP-LIF for extracellular vesicle isolation, subtype fractionation, and profiling.
