Signal transducer and activator of transcription 3 (STAT3) hyperactivation correlates with aberrant follicular helper T (Tfh) differentiation in patients with rheumatoid arthritis (RA). Statistics showing the relationship between the frequencies of indicated CD4+ T cell subsets with the phosphorylated STAT3 (pSTAT3) expression in total CD4+ T cells (A) or in each individual subsets (B) in the peripheral blood mononuclear cells from patients with RA. The correlation was determined using Spearman’s correlation coefficient.
