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
Tight junctions (TJs) are the key determinant of barrier function in the mammary gland, with their disruption being associated with the pathogenesis and progression of mastitis, especially in the case of Staphylococcus aureus (S. aureus) infection. This study investigated whether selenium (Se) could attenuate S. aureus-induced mastitis by inhibiting inflammation and protecting mammary gland TJs in mice. The expression profiles of S. aureus-infected gland tissues derived from the gene expression omnibus dataset were analyzed. We found cytokine production, cell junctions, the nuclear transcription factor-κB (NF-κB) signalling pathway, and inflammatory responses associated with the differentially expressed genes, as revealed by Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) enrichment analyses. Se reduced the mRNA expression and production of inflammatory cytokines, including tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6), and decreased phosphorylation levels of the NF-κB complex. Moreover, Se alleviated structural damage and microvillus injury in mammary glands. Immunohistochemical staining revealed that Se increased the expression of Claudin-3; Western blot analysis revealed increased protein levels of Occludin and Tricellulin in the group supplemented with dietary Se. In summary, Se counteracted TJ disruption and attenuated NF-κB-mediated inflammatory responses in S. aureus-infected mouse mammary glands.
