Carotid artery and IVC thrombosis in wild-type and low-TF mice. (A) The percentage of animals with patent arteries in each group are plotted in a Kaplan-Meier graph as a function of time after initiation of photochemical injury. (B) Mean occlusion times following arterial injury. (C) Thrombus mass measured 48 hours after IVC ligation. *P < .01 versus wild-type mice.
