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

The development of targeted nanotherapeutics capable of restoring chondrocyte homeostasis represents a major challenge in osteoarthritis (OA) treatment. In this study, we engineered a transforming growth factor-β (TGF-β) receptor-targeted exosome-nanoparticle hybrid system (TGFβ-Exo-NP) derived from chondrocytes and systematically evaluated its therapeutic efficacy and molecular mechanism. TGFβ-Exo-NP displayed uniform nanoscale morphology, favorable surface charge, and controlled release properties, with robust chondrocyte-specific uptake mediated by transforming growth factor-β receptor (TGF-βR) targeting. Functionally, TGFβ-Exo-NP markedly restored mitochondrial function, increased adenosine triphosphate (ATP) production, and inhibited apoptosis and pyroptosis in IL-1β-challenged chondrocytes, while promoting anabolic extracellular matrix synthesis. Integrated ChIP-seq, RNA-seq, and proteomic analyses demonstrated that TGFβ-Exo-NP activated a SOX3-driven epigenetic program involving histone H3 lysine 4 trimethylation (H3K4me3) enrichment and SIRT5 upregulation, thereby reprogramming mitochondrial metabolism. WDR5 was identified as a key exosomal effector protein required for chromatin activation and metabolic recovery.
