  1. Effects on coagulation of the coagulation factors fibrinogen, fibrinogen with factor XIII (Fibrinogen + FXIII) or no addition of coagulation factor (Control). Data are estimated marginal means. COT1 and COT2 are coagulation time 1 and 2, respectively. The maximal clot strength is presented as G'max for Fib1 (without platelet inhibition) and G'max for Fib2 (with platelet inhibition). Platelet-dependent clot strength is presented by the difference between G'max for Fib1 and that of Fib2, denoted as G'max Fib1-2. ** and *** stands for p < 0.01 and p < 0.001, respectively, when the addition of coagulation factor was compared to the control group. †† and ††† stands for p < 0.01 and p < 0.001, respectively, when the addition of fibrinogen alone was compared to the addition of fibrinogen with FXIII.
