Serum von Willebrand factor (VWF) levels are higher in children with cerebral malaria (CM) than uncomplicated malaria (UM) and are elevated even in children with asymptomatic parasitemia. Values are reported as a relative percent (%) of normal. Gray vertical bars indicate the median, and the bracketed numbers indicate number of samples tested. A, Serum VWF levels in children with CM, children with UM, and community children (CC). B, Serum VWF levels in asymptomatic community children, according presence or absence of Plasmodium falciparum in study participants as detected by microscopy (Smear) or polymerase chain reaction (PCR).
