Correlation of Treg, Th17, and CD4 + T cell subset ratios with related clinical indicators in the RA-CAD (n = 54), and pure RA (n = 43) groups. A Heatmap of correlation of Treg, Th17, and CD4 + T cell subset ratios and related clinical indicators in RA-CAD patients. B Heatmap of correlation of Treg, Th17, and CD4 + T cell subset ratios and related clinical indicators in pure RA patients. C–H Correlation between Treg, Th17, and typical clinical indicators in RA-CAD patients. Correlations were assessed using Spearman’s rank test. *p < 0.05, **p < 0.01
