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
Microglia function as a vital constituent in the maintenance of brain homeostasis. Aberrant microglial activation, however, may contribute to neurodegenerative diseases. Lithospermic acid (LA) is a plant-derived polycyclic phenolic carboxylic acid isolated from Salvia miltiorrhiza. The present study investigated the potential effects of lithospermic acid on LPS-induced neuroinflammation in BV2 microglial cells and determined the mechanism of action of this compound. Cells were pre-treated with lithospermic acid for 1 h and incubated with LPS for 24 h. qPCR, immunofluorescence, and immunoblot assays were used to determine the expression of iNOS, COX2, NF-κB p65, and HSP90 expression. ELISA was employed to measure the production of pro-inflammatory cytokines. Lithospermic acid dramatically reduced LPS-stimulated cell migration and decreased NF-κB p65 nuclear translocation. Furthermore, lithospermic acid also markedly decreased the production of pro-inflammatory cytokines, including IL-6, IL-1β, and TNF-α in a dose-dependent manner. Additionally, lithospermic acid inhibited NO and PGE2 production in response to LPS, and it also inhibited the expression of iNOS and COX2 in a dose-dependent manner. Molecular docking and experimental verification have demonstrated that lithospermic acid inhibits the activity and expression of HSP90. Small interfering RNA knockdown of HSP90 expression, which abrogated LPS-induced inflammation. These findings suggest that the lithospermic acid targeting HSP90 attenuates LPS-induced inflammatory response via the NF-κB signalling pathway in BV2 microglial cells. Collectively, lithospermic acid may offer therapeutic benefits for neurodegenerative disorders associated with microglial activation and could serve as a potential inhibitor/agent for the treatment of neuroinflammation.
