However, there was no significant difference in the plasma levels of IFN-γ (median, 4.59 pg/mL, IQR 3.93–59.03 pg/mL versus 4.15 pg/mL, IQR 3.61–6.29 pg/mL, p = 0.50, Figure 2B), MCP-1 (median, 94.68 pg/mL, IQR 57.03–98.21 pg/mL versus median 105.80 pg/mL, IQR 82.91–148.50 pg/mL, Figure 2C), or IP-10 (median 2.80 ng/mL, IQR 0.50–3.10 ng/mL versus median 4.80 ng/mL, IQR 2.00–204.60 ng/mL, Figure 2D) between RA patients with severe and non-severe HZ. The gene discussed is CXCL10; the disease is rheumatoid arthritis.
