Transcriptomic analysis of neutrophils in RA patients compared with HC (control). A Venn diagram representing shared genes from three mRNA expression profiling datasets GSE154474, GSE93776, and GSE116899. B, C Box plots visualization of GSE154474, GSE93776, and GSE116899 data pre- and post-normalization. D PCA of normalized expression data. Volcano plots and heat maps of DEGs based on normalized data: E, H DEGs between RA SF and RA PB; F, I DEGs between RA PB and HC PB; G, J DEGs between RA SF and HC PB
