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
The study aimed to investigate the therapeutic potential of 1,1-dimethyl-4-phenylpiperazinium iodide (DMPP), an agonist of nicotinic acetylcholine receptor (nAChR), in treating acute lung injury (ALI) induced by lipopolysaccharide (LPS). A murine ALI model was developed utilizing intraperitoneal injection of LPS. We evaluated the therapeutic efficacy of DMPP treatment in LPS-induced lung injury using various approaches, including pathohistological evaluation, appraisal of pulmonary edema, and measurement of inflammatory cytokine levels and their associated pathways within lung tissues. The gene chip data of LPS-induced acute lung injury mice were retrieved from the Gene Expression Omnibus (GEO) database for gene differential expression analysis and Gene Set Enrichment Analysis (GSEA) analysis. The impact of DMPP on glycocalyx shedding was assessed by measuring the expression levels of syndecan-1 (SDC-1) and matrix metalloproteinase-9 (MMP-9). DMPP treatment significantly improved pathomorphological changes and pathological lung injury scores in the LPS-induced ALI mouse model. The genes expressed differentially in the LPS-induced ALI group in GSE2411 were found to be involved in multiple processes, including the NF-κB signaling pathway, NOD-like receptor signaling pathway, Toll-like receptor signaling pathway, as well as the JAK-STAT signaling pathway. DMPP treatment effectively downregulated pro-inflammatory cytokines, suppressed the NF-κB signaling pathway, and effectively restrained the LPS-induced upregulation of MMP-9 and shedding of syndecan-1, thereby contributing to the preservation of endothelial glycocalyx and attenuation of endothelial barrier dysfunction. The administration of DMPP has been shown to confer protection against LPS-induced acute lung injury via a cholinergic anti-inflammatory pathway, which effectively inhibits endothelial glycocalyx degradation.
