Data represented as mean ± SD; n = 3. Statistical significance is denoted with *P < .05 for differences between 1.0 and 10.0 U/mL thrombin and #P < .05 for comparison between γA/γA and γA/γ′ supplemented fibrinogen-deficient plasmas with the same thrombin concentration. CFR, clot formation rate; CT, clot formation time; G, storage modulus; MCF, maximum clot firmness.
