CD163 and hemorrhagic fever with renal syndrome: A Spearman correlation analysis demonstrated that the increasing sCD163 level was positively correlated with the increasing monocyte absolute counts (Figure 5A, r = 0.6673, P<0.0001), CD14++CD16+ monocytes (Figure 5B, r = 0.5779, P<0.0001) and the CD163 expression on CD14++CD16+ monocyte (Figure 5C, r = 0.6245, P<0.0001) in the HFRS patients.
