Predictive value of sP-selectin and FVII in the LAC-positive subpopulations. (A) Histograms (percentage) of sensitivity, specificity, PPV, NPV for sP-selectin (ng/mL), FVII (%) and the combination of sP-selectin and FVII in the indicated subpopulations of patients positive for LACs (including those with LAC titer = 0 AU/mL). (B) 2 × 2 tables for sP-selectin (ng/mL) and FVIIa (%) and their combination in the indicated subpopulations with low LAC titer (AU < 10), low anti-β2GPI titer (< 3 GAU/mL) and the subpopulation with low LAC titer or low anti-β2GPI titer, as indicated (including those with LAC titer = 0 AU/mL). P values calculated with Fisher exact test are indicated for each 2 × 2 table.
