Model-predicted restoration of normal thrombin and fibrin generation in diluted plasma by clotting factor supplementation. “Fg” stands for supplementation with fibrinogen, “PCC” denotes supplementation with PCC-AT (a combination of the factors II, IX, X, and antithrombin), and “Fg/PCC” denotes simultaneous supplementation with fibrinogen and PCC-AT. A: Clotting was initiated with 2 pM TF. B: Clotting was initiated with 5 pM TF. C: Clotting was initiated with 10 pM TF. Here, the blue and red lines for fibrin generation practically coincide, as do the orange and red lines for thrombin generation.
