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

Ischaemic brain stroke is among the leading causes of death and disability worldwide. However, the current treatments have a limited time window and regeneration potential. Clinically relevant human platelet-derived extracellular vesicles (EVs) offer potential neuroprotective treatment for stroke. Here, the neuronal uptake of carboxyfluorescein succinimidyl ester (CFSE)-labelled EVs was confirmed by confocal imaging and three-dimensional (3D) image analysis with Imaris software. The results showed that human induced pluripotent stem cell (hiPSC)-derived neurons can internalize EVs. We also show the colocalization of EVs with cellular organelles: early endosomes and lysosomes. We used an in vitro human model of stroke to study the effects of hypoxia on neurons. After hypoxia, the activity of the neurons, including spiking and bursting, decreased. However, the activity was restored after 72 h of reperfusion. EVs did not affect neuronal activity acutely, but during long-term follow-up, neurons showed increased activity. Together, our findings provide insights into the effects of platelet-derived EVs on neuronal uptake, morphology and functionality and changes after hypoxic insult in an in vitro human model.
