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
Objective: Juvenile dermatomyositis (JDM) is a complex autoimmune disease, and its pathogenesis remains poorly understood. Building upon previous research on the immunological and inflammatory aspects of JDM, this study aims to investigate the role of pyroptosis in the pathogenesis of JDM using a comprehensive bioinformatics approach. Methods: Two microarray datasets (GSE3307 and GSE11971) were obtained from the Gene Expression Omnibus database, and a list of 62 pyroptosis-related genes was compiled. Differential gene expression analysis and machine learning analysis were performed to identity the hub pyroptosis-related differentially expressed genes (PR-DEGs). Functional enrichment analysis, immune cell infiltration analysis, gene set variation analysis (GSVA), and gene set enrichment analysis (GSEA) were performed to elucidate the potential roles of PR-DEGs in JDM pathogenesis. Results: A total of 2526 common DEGs were identified, among which 12 PR-DEGs were identified, with CASP1, IRF1, NOD2, and PYCARD identified as hub PR-DEGs. These genes were involved in cytokine production, inflammasome activity, necroptosis, NOD-like receptor signaling, and TNF signaling. Immune infiltration analysis showed increased pro-inflammatory immune cell infiltration in JDM patients, with PR-DEGs positively correlated with various immune cell types. GSVA and GSEA analyses demonstrated the involvement of PR-DEGs in multiple inflammation and immunity-related pathways, with the NOD-like receptor signaling pathway playing a central role. Conclusion: This study highlights the crucial role of pyroptosis in the pathogenesis of JDM, with the identified PR-DEGs potentially contributing to disease development and progression by regulating key inflammatory and immune-related pathways.
