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
Rotenone-induced neurotoxicity in SH-SY5Y cells is an essential hallmark of neurodegenerative diseases like Alzheimer's disease (AD) and Parkinson's disease (PD). β-Caryophyllene (BCP), a cannabinoid receptor 2 (CB2) agonist, has anti-inflammatory, antioxidant, and cytoprotective efficacy. The involvement of the GSK-3β/NRF2/HO-1 axis in neuroprotection has garnered attention as a possible mechanism for BCP to exhibit multitargeted neuroprotective effects. Hence, this study investigates the effects of BCP against rotenone-induced neurotoxicity and apoptosis in SH-SY5Y cells, focusing on the involvement of the GSK-3β/NRF2/HO-1 signaling pathway. Initially, we performed the in silico molecular docking of BCP with GSK-3β, NRF2, and HO-1 proteins to ensure the degree of binding affinities. The in vitro MTT assay was performed to evaluate cell viability, followed by the assessment of biomarkers such as LDH leakage, oxidative stress, reactive species, caspase 3 activity, pro-inflammatory markers, and GSK-3β, NRF2, and HO-1 proteins in BCP, as well as specific receptor modulators (chir98023 and quercetin) against the rotenone pre-treated cells. In silico molecular docking studies revealed that BCP exhibits a strong binding affinity for GSK-3β, NRF2, and HO-1 proteins. Also, in vitro studies revealed that BCP (100 µg/ml), as compared to the rotenone-treated group, significantly restored cell viability (72%). Moreover, BCP significantly modulates cell cytotoxicity (LDH leakage), pro-apoptotic, pro-inflammatory, reactive species, and oxidative stress markers. Molecular docking established robust binding affinities of BCP with GSK-3β, NRF2, and HO-1 proteins. Furthermore, protein estimation by ELISA confirmed the BCP-mediated modulation of these pathways. These findings suggest that BCP protects SH-SY5Y cells from rotenone-induced neurotoxicity, offering a potential therapeutic candidate for neurodegenerative diseases like AD.
