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
Microglial activation-induced neuroinflammation and impaired neuronal mitophagy are recognized as pivotal pathogeneses in Parkinson's disease (PD). However, the role of microglial mitophagy in microglial activation during PD development remains unclear, and therapeutic interventions targeting this interaction are lacking. Rhapontigenin (Rhap), a stilbenoid enriched in Vitis vinifera, exhibits dual anti-neuroinflammatory and mitophagy-enhancing properties, but its therapeutic potential and mechanisms in PD are unexplored. This study aimed to investigate the therapeutic efficacy of Rhap on neurodegeneration in a PD model and explore its underlying mechanism. Here, we showed that Rhap administration significantly ameliorated motor deficits, dopaminergic neuron loss, and neuroinflammation in MPTP-induced PD mice. Mechanistically, Rhap suppressed neuroinflammation by inhibiting the cGAS-STING-NF-κB signaling axis in both PD model mice and MPP⁺-induced BV2 microglia. Crucially, its anti-inflammatory effects depend on the PINK1-mediated enhancement of microglial mitophagy to control cytosolic mtDNA leakage. Specifically, Rhap bound to PINK1 strengthened the PINK1-DRP1 interaction, promoted mitochondrial fission in damaged organelles, and enhanced mitophagy clearance. This mitophagy activation prevents cytosolic leakage of mitochondrial DNA (mtDNA), thereby attenuating mtDNA-cGAS-STING-NF-κB-derived neuroinflammation and subsequent neurodegeneration in PD. PINK1 deficiency in BV2 microglia abolished Rhap's ability to suppress mtDNA-cGAS-STING-NF-κB activation and enhance mitophagy. Overall, our study reveals a previously unrecognized mechanism by which Rhap ameliorates PD-associated neurodegeneration through dual modulation of PINK1/DRP1-dependent microglial mitophagy and the mtDNA-cGAS-STING-NF-κB neuroinflammatory axis, suggesting a potential therapeutic strategy for PD and related neurodegenerative disorders.
