Bleeding and rebleeding time in B6, A/J, Lepob, Plg-/- and PAI-1-/- mice. Panel A, B: Bleeding time (seconds) and Panel C, D: Rebleeding time (seconds). To determine statistical differences, values from B6 and A/J and from WT and Plg-/- littermates were compared with a t-test, and values from B6, PAI-1-/- and Lepob were compared by a one-way ANOVA and a Newman-Keuls post-test. Symbols indicate a significant difference (*P < 0.05, **P < 0.01, ***P < 0.001) between B6 or WT mice. Values are the mean ± SEM of 10–34 mice per genotype.
