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
Introduction: Exposure to sevoflurane in neonatal rats disrupts energy metabolism during brain development, which is associated with anesthetic-induced neurodevelopmental toxicity. Hepatic fatty acid metabolism plays a critical role in response to brain energy supply. However, how sevoflurane exposure affect hepatic fatty acid metabolism remains unclear. Methods: We employed multiple analytical methods in neonatal rats following sevoflurane exposure to: (1) Analyze alterations in hepatic fatty acid metabolism-related gene expression and immune cell infiltration; (2) Decipher associated metabolic pathways, including cholesterol metabolism and the expression changes of Dhcr24; (3) Conduct enrichment analyses (GO, KEGG, GSEA, GSVA) and functional investigations via Friends analysis; (4) Construct mRNA-miRNA-lncRNA regulatory networks; (5) Identify key genedrug small molecule interactions based on IC50 differences and (6) Verify the expression of key genes involved in fatty acid metabolism and the activation of immune cells. Results: Significant alterations were observed: (1) Identification of 15 key fatty acid metabolism-related differentially expressed genes (DEGs and RT-PCR); (2) Significant enrichment of 40 GO terms and 5 KEGG pathways; (3) GSEA/GSVA revealed 130 up-regulated and 62 down-regulated GO gene sets, along with 5 up-regulated and 2 down-regulated KEGG pathways; (4) Friends analysis highlighted Dhcr24 as a critical player in cholesterol metabolism; (5) Network analysis identified pivotal mRNA and lncRNA nodes within the regulatory networks; (6) Screening yielded 43 key gene-drug combinations with significant IC50 differences; and (7) Immunofluorescence confirmed the activation expression of relevant immune cells. Bioinformatics analysis pinpointed diagnostic biomarkers for both hepatic fatty acid metabolism perturbations and immune cell infiltration following exposure. Discussion: These findings demonstrate that neonatal sevoflurane exposure profoundly affects hepatic fatty acid metabolism and immune cell infiltration, involving specific key genes (including Dhcr24), perturbed pathways, and regulatory networks. The identified biomarkers and potential therapeutic targets provide a crucial foundation for developing more specific countermeasures against sevoflurane-induced neurodevelopmental toxicity, potentially via targeting the liver-brain metabolic axis.
