Correlation between PlGF and markers of hemolysis and inflammation. (A) PlGF is correlated with lactate dehydrogenase levels (r = 0.36, P = .002). (B) PlGF is correlated with reticulocyte count (r = 0.32, P = .007). (C) PlGF is inversely correlated with hemoglobin levels (r = −0.44, P = .001). (D) PlGF is correlated with soluble VCAM (r = 0.42, P < .001). Data shown with regression line. Spearman correlation data are shown in Table 2.
