sP-selectin titer and FVII levels in patients with LACs. (A) Box-and-whisker plots for sP-selectin (ng/mL) and FVII (%) in patients without or with TECs in the (INR/FVII corrected) total patient population (n = 54),and in the subpopulation with low LAC titer or anti-β2GPI IgG titer (n = 37), as indicated. P value, calculated with the Mann-Whitney test, represents the comparisons between the experimental groups with and without TECs. (B) Dot plot of the sP-selectin titer (ng/mL) versus FVII (%) for these patients (n = 54). (C) Dot plot of the sP-selectin titer (ng/mL) versus FVII (%) for the subpopulation of patients positive for LACs with low LAC titer or low anti-β2GPI IgG titer (n = 37). In both cases, the thick lines represent the cutoff value for high sP-selectin titers (≥ 79 ng/mL) and FVII titers (≥ 104%).
