Increased Circulating Th1 and Tfh1 Cell Numbers Are Associated with Disease Activity in Glucocorticoid-Treated Patients with IgG4-Related Disease

Figure 3

Correlation analysis of circulating Th cell subsets with serum IgG4 and IgG4-RD RI in IgG4-RD patients. Serum IgG4 concentrations of all IgG4-RD patients () were measured. Correlation analyses were conducted between absolute numbers (per μL) of Th subsets and serum IgG4 (up) or IgG4-RD RI scores (down) in IgG4-RD patients. Each plot represented the data of a patient. The Spearman test’s and values for each parameter were listed. The values were Spearman’s correlation coefficients. For values less than 0.05, data were presented as scatter plots with a linear fit.
