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
aimAlzheimer's Disease (AD) is a neurodegenerative condition with poorly understood mechanisms and few effective treatments. β-asarone has shown potential in AD management, though its molecular actions require further clarification. This study investigates the mechanisms through which β-asarone exerts its effects using both animal and cellular models.
methodsIn vivo, the 3×Tg-AD mice were administered β-asarone for 8 weeks. Learning and memory abilities were assessed via the Morris water maze and step-down tests. Histomorphological examination, immunofluorescence, immunohistochemistry, ELISA, transmission electron microscopy, and Western blotting were employed to detect pathological changes, neuroinflammation, and protein expression of relevant signaling pathway molecules. In vitro, Aβ was used to culture BV-2 cells to mimic the brain microenvironment in Alzheimer's disease; changes in neuroinflammation, autophagy, and NLRP3 inflammasome-related proteins were observed after treatment with β-asarone.
resultsThe administration of β-asarone resulted in enhanced cognitive performance in 3×Tg-AD mice, alongside a reduction in microglial apoptosis induced by Aβ. Additionally, β-asarone diminished the accumulation of Aβ and phosphorylated Tau, ultimately supporting neuronal survival. In both the hippocampal tissue and BV-2 cell models, treatment with β-asarone led to a downregulation of neuroinflammatory markers and modulation of autophagy-related proteins (Beclin-1, P62, ATG5, LC3-II/I), while concurrently suppressing components of the NLRP3 inflammasome (NLRP3, ASC, Caspase-1, cleaved Caspase-1). Notably, the autophagy inhibitor 3-MA counteracted the inhibitory effects of β-asarone on NLRP3 activation.
conclusionβ-Asarone attenuates AD-related neuroinflammation by activating autophagy to inhibit NLRP3 inflammasome assembly.
