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

Stroke is a leading cause of death and disability. The therapeutic potential of mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) has shown considerable promise in rodent models of stroke. However, the therapeutic efficacy and safety of clinical-scale MSC-EVs for ischemic stroke are not well elucidated, especially in non-human primates. We developed a scalable production method for MSC-EVs using a 3D bioprocessing platform. EVs were isolated with a filter and tangential flow filtration and characterized using electron microscopy, nanoparticle tracking analysis, nanoflow cytometry analysis, proteomic and lipidomic analysis using mass spectrometry, and RNA sequencing. We determined the appropriate dosage and frequency of intravenous administration of EVs in a mouse stroke model. A biodistribution study of the selected dose regimen was performed using the internal cargo of EVs, human mitochondrial DNA. We then confirmed the efficacy of EVs in a marmoset stroke model. Improvement in behavioural tests and MRI-based neuroplasticity were compared between the control and EV groups through blinded evaluation. The proteome profiles of the infarcted hemisphere were also evaluated. EV products showed suitable lot-to-lot consistency. In a mouse stroke model, intravenous administration of a dose of 6 × 10
