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
Pediatric sepsis is a serious disease characterized by multiple organ failure. Due to its unique pathogenesis, its clinical mortality rate is very high. This study systematically evaluated the value of efferocytosis related genes in the diagnosis of sepsis in children. We downloaded gene expression profiles related to pediatric sepsis from the gene expression omnibus database, identify differentially expressed genes (DEGs) by limma R package, and retrieve adult sepsis gene expression profiles to determine the specificity of pediatric sepsis biomarkers. Selected pediatric sepsis specific genes from these profiles and used clusterProfiler for Kyoto Encyclopedia of Genes and Genomes (KEGG), gene ontology, and Reactome databases for functional enrichment. Genesets related to Efferocytosis was searched in the KEGG database, and the intersection with pediatric sepsis specific genes was considered as pediatric sepsis-efferocytosis genes. Immune infiltration analysis was performed using the CIBERSORT package. Constructed a protein-protein interaction (PPI) network and screened for hub genes in pediatric sepsis-efferocytosis genes. Further select diagnostic markers through gene expression and receiver operating characteristic (ROC) curve. We identified a total of 281 DEGs specific to pediatric sepsis, which are enriched in pathways such as phagosome, autophagy and efferocytosis. We found that the efferocytosis pathway is significantly up-regulated in pediatric sepsis, while this pathway is not significant in adult sepsis. We noticed that 12 types of immune cells infiltration levels including macrophages in pediatric sepsis patients. We selected the top 20 hub genes with PPI network. By overlapping hub genes with pediatric sepsis-efferocytosis genes, we obtained 2 hub pediatric sepsis-efferocytosis genes (ALOX5, CD36). The ROC curve suggested that these genes may be potential diagnostic markers for pediatric sepsis. We have identified ALOX5 and CD36 as efferocytosis related genes associated with pediatric sepsis, which can reliably identify pediatric sepsis and provide prospective clinical references for the pathogenesis of pediatric sepsis.
