Figure 3. . Correlations among serum DPP4 activity and known prognostic factors of COVID-19 disease mortality.

Figure 3. 

(A) DPP4 versus albumin (R: 0.6428; p < 0.0001). (B) DPP4 versus absolute lymphocyte count (R: 0.4099; p < 0.0001). (C) DPP4 versus age (R: -0.4721; p < 0.0001). (D) DPP4 versus C-reactive protein (CRP) (R: -0.5815; p < 0.0001). (E) DPP4 versus D-dimer (R: -0.5867; p < 0.0001). The axis for CRP and D-dimer are logarithmically scaled and fitted.
