Phosphatidylserine externalization. Histograms representing the percentage of annexin-V-positive RBCs. Data are the mean ± SD of 40 HDs (22 male and 18 female) and 56 MetS patients (31 male and 25 female). An increased positivity was detectable in RBCs from MetS patients with respect to those from healthy donors (λ) ^• P < 0.05. Analyzing separately RBCs from males and females, a significant increased positivity was detectable only in RBCs from males with MetS with respect to healthy males. °P < 0.01.
