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
Recent studies have highlighted the efficacy of platelet-rich plasma-derived exosomes (PRP-Exo) in managing osteoarthritis (OA). This research aimed at exploring the effect and mechanism of PRP-Exo-mediated intervention in chondrocyte pyroptosis and knee osteoarthritis. In this study, PRP was collected from human volunteers and rats, and the PRP-Exo was extracted, which was employed in the in vitro and in vivo OA model. The molecular interaction was analyzed by luciferase reporter assay, Chromatin immunoprecipitation and Electrophoretic Mobility Shift Assay experiment. Cell pyroptosis was analyzed by flow cytometry and biomarkers detection. Degrees of cartilage injury were detected using Alcian Blue, Safranin O Fast Green, and Toluidine Blue O staining. Our results showed that PRP-Exo had a similar effect with PRP on alleviating chondrocyte pyroptosis and OA progression. PRP-Exo functioned by transferring miR-25-3p to chondrocyte, which targeting to MAP4K2 and regulating Hippo pathway. MiR-25-3p inhibition weaken the effect of PRP-Exo, while MAP4K2 overexpression reversed the effect of miR-25-3p overexpression. Besides, TNFAIP3 was confirmed as a downstream molecular of MAP4K2/Hippo pathway. The effect of miR-25-3p was also confirmed in a rat OA model. Collectively, this study elucidated that PRP-Exo derived miR-25-3p alleviated chondrocyte pyroptosis and OA progression by regulating the MAP4K2/Hippo/TNFAIP3 pathway.
