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
Excessive glutamate in the central nervous system is a key pathogenic mechanism in neurodegenerative disorder. This study investigated the neuroprotective effect of acrovestone (AVT), an acetophenone dimer from Acronychia pedunculata, and its underlying mechanism in glutamate-induced neuroblastoma SH-SY5Y cells. The protective effect of AVT was evaluted through cell viability assay and analysis of apoptosis-related protein expression via Western blot analysis. Our finding revealed that AVT significantly improved cell viability under glutamate induced excitotoxicity conditions. Mechanistic investigations demonstrated that AVT attenuated the activation of pro-apoptotic proteins including ERK1/2, Bim, BAX, caspase-3, caspase-7, and caspase-9. Concurrently, AVT upregulated the expression of anti-apoptotic proteins Bcl-2 and Bcl-xL. Furthermore, AVT modulated the Akt/FoxO3a signaling pathway, alleviating acute oxidative stress caused by glutamate exposure in SH-SY5Y cells. These results suggest that AVT inhibits glutamate-induced neurotoxicity by modulating apoptosis signaling pathway, highlighting its potential as a therapeutic candidate for preventing neurodegenerative diseases.
