Fig. 3From: The host cellular immune response to cytomegalovirus targets the endothelium and is associated with increased arterial stiffness in ANCA-associated vasculitisCD4+CD28null T-cell expansion correlates with increased arterial stiffness and blood pressure parameters. CD4+CD28null T-cell percentage correlated with increased systolic blood pressure (a), pulse pressure (b), a surrogate marker of arterial stiffness, and carotid-to-femoral pulse wave velocity (c) (n = 53)Back to article page
