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

Background: Korean black ginseng, a specially processed ginseng through repeat steaming and drying, has various pharmacological effects. However, its role Purpose and methods: This study examined whether Korean black ginseng extract (BGE; 50 and 100 mg/kg, orally, 18 weeks) may mitigate cognitive impairment in a 5xFAD mouse model of Alzheimer's disease (AD). Results: BGE significantly improved cognitive performance in 5xFAD mice, associated with reduced Aβ accumulation in the frontal cortex and hippocampus. BGE suppressed microglial and astrocytic activation, alongside the downregulation of pro-inflammatory cytokines (interleukin-6 and tumor necrosis factor-α) and enzymes (cyclooxygenase-2 and inducible nitric oxide synthase). These changes coincided with the inhibition of key inflammatory signaling pathways, such as p38 mitogen-activated protein kinase (MAPK), nuclear factor kappa B (NF-κB)/p65, signal transducer and activator of transcription (STAT) 3, and NOD-like receptor protein 3 (NLRP3) inflammasome. Furthermore, BGE reduced the generation of reactive oxygen species and enhanced the nuclear-E2-related factor 2 (Nrf2)-heme oxygenase 1 (HO-1) signaling pathway in the brains linked to the downregulation of toll-like receptors (TLR)-2 and TLR-4 in the brain. Conclusion: Taken together, BGE could improve AD-related cognitive decline and neurodegeneration by simultaneously regulating anti-inflammatory pathways (p38 MAPK/NF-κB/STAT3 and NLRP3 inflammasome) and an antioxidant pathway (Nrf2/HO-1) via modulation of TLR2/4.
