TG and thrombin dynamics parameters measured at 5 pM TF in APS patients with and without prior thrombosis. TG peak height (A) and ETP (B) and total prothrombin conversion (C) and maximum rate of prothrombin conversion (D) were significantly higher in APS patients with prior thrombosis than in patients without a history of thrombosis. There was no difference between a history of venous thrombosis (green dots), arterial thrombosis (blue dots), or a combination of both (red dot). ROC curves were plotted for each of the variables. *P < .05 and **P < .01 compared with the control group using a 2-sided Mann-Whitney U test.
