1 · What the graph read from it

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.

2 · The registry

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

backgroundGrowing evidence points a connection between Primary Sjögren's Syndrome (pSS) and Primary Biliary Cholangitis (PBC). This study seeks to identify the crosstalk genes between them.

methodTranscriptomic datasets for pSS (GSE66795) and PBC (GSE119600) were sourced from the Gene Expression Omnibus (GEO) database. Common genes between these two conditions were detected using Differential Expression Analysis and Weighted Gene Co-expression Network Analysis (WGCNA). Potential crosstalk genes were pinpointed through Least Absolute Shrinkage and Selection Operator (LASSO) regression. Validation of these genes were performed through single-sample gene set enrichment analysis (ssGSEA), multivariable logistic regression, and single-cell transcriptome analysis.

resultDifferential expression analysis showed 339 commonly upregulated DEGs in both pSS and PBC. WGCNA analysis revealed 11 modules associated with pSS and 7 modules associated with PBC. Subsequently, 56 core genes were found to overlap between the genes identified by differential expression analysis and WGCNA. LASSO regression identified CX3CR1, ELF1, CUL1, PARP3, DDX60, SP140L, and MUC1 as pivotal crosstalk genes for both pSS and PBC. Moreover, ssGSEA analysis and multivariable logistic regression underscored the potential of these 7 genes as crosstalk genes. Single-cell analyses revealed higher proportions of NK cells, CD4+ T cells, and CD8+ T cells in pSS patients, with prominent expression of CX3CR1, ELF1, CUL1, PARP3, DDX60, SP140L, and MUC1 in these cells.

conclusionOur study identified CX3CR1, ELF1, CUL1, PARP3, DDX60, SP140L and MUC1 as crosstalk genes between pSS and PBC, and highlighted the critical role of NK cells, CD4+ T cells and CD8+ T cells in disease mechanisms.
