HDGFL2 and parasitic infectious disease: Markers of parasite burden such as peripheral blood parasitemia (Ret+ CM IgG: Rs = 0.204, P = 0.043), P. falciparum cfDNA (Pf cfDNA) (UM IgG: Rs = 0.323, P = 0.0002; Ret+ CM: Rs = 0.286, P = 0.004), and total parasite load (Pf HRP2) (UM: Rs = 0.317, P = 0.005) were positively correlated with anti–PF4/P IgG levels (Supplemental Table 1).
