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
While glutamate, a key neurotransmitter in the central nervous system, is fundamental to neuronal viability and normal brain function, its excessive accumulation leads to oxidative stress, contributing to neuronal damage and neurodegenerative diseases. In this study, we investigated the effect of β-lapachone (β-Lap), a naturally occurring naphthoquinone, on glutamate-induced injury in HT22 cells and explored the underlying mechanism involved. Our results show that β-Lap significantly improved cell viability in a dose-dependent manner. Additionally, β-Lap exhibited a significant antioxidant activity, reducing intracellular reactive oxygen species levels and restoring glutathione levels. The antioxidant capacity of β-Lap was further demonstrated through 2,2-Diphenyl- 1-picrylhydrazyl (DPPH) and 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging assays. Western blot analysis revealed that β-Lap upregulated brain-derived neurotrophic factor (BDNF) and promoted the phosphorylation of tropomyosin receptor kinase B (TrkB), extracellular signal-regulated kinase (ERK), and cAMP response elementbinding protein (CREB), which were downregulated by glutamate. Furthermore, β-Lap enhanced the cellular antioxidant molecules, nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1). In conclusion, β-Lap can protect HT22 cells against glutamate-induced injury by activating the BDNF/TrkB/ERK/CREB and ERK/Nrf2/HO-1 signaling pathways, suggesting its therapeutic potential for neurodegenerative diseases.
