Plasma levels of von Willebrand factor (vWF) in the patient groups at admission. a shows plasma levels of vWF in patients with HIV infection with febrile symptoms but without malaria (n = 58), patients with falciparum malaria without (n = 61) and with HIV infection (n = 70). Data are given as median and 25-75th percentiles. ^††p < 0.01 versus HIV without malaria and malaria without HIV. The horizontal dashed line and shaded area represent median levels and 25-75th percentiles in healthy controls (n = 52). vWF levels were significantly raised compared with levels in controls in all three groups of patients (p < 0.001 for all comparisons). b shows the correlation between plasma levels of IL-27 and vWF in patients with falciparum malaria with (n = 70) and without (n = 61) co-infection with HIV
