Ultracentrifugal separation, characterization, and functional study of extracellular vesicles derived from serum-free cell culture.
Article in STAR protocols, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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) play important roles in extracellular trafficking and signaling. Here, we separate EVs by differential centrifugation. EVs separated by this approach are called large EVs (l-EVs) and small EVs (s-EVs), reflecting particle size, which sediment based on different ultracentrifugation forces. The resulting EVs can be quantified and analyzed using nanoparticle tracking analysis, immunoblotting, and functional assays. This protocol was applied to a suspension cell line with high transfection efficiency adapted to a high-density, serum-free culture. For complete details on the use and execution of this protocol, please refer to Nishimura et al. (2021).
