CXCL10 and hemorrhagic fever with renal syndrome: Spearman correlation analysis showed that the increasing level of CXCL10 was correlated with the increasing BUN (r = 0.345, P < 0.005), Crea (r = 0.138, P < 0.05), and WBC (r = 0.341, P < 0.005) and the decreasing PLT counts (r = −0.500, P < 0.005) in HFRS patients (Figure 1(c)).
