Statistics Data are presented as mean ± SEM. The statistical analysis for comparisons between A/J and B6 mice and between wild-type (WT) and Plg-/- littermates was compared with a two-tailed t-test. Differences among B6, Lepob, PAI-1-/- mice were determined by a one-way ANOVA and a Newman-Keuls post-test. A value of P < 0.05 was considered significant. The statistical analysis for comparisons between B6 mice and CSS were determined with two-tail t-tests and the level of the significant P-values (see figure legends) determined with a Bonferroni correction to account for multihypothesis testing [13].
