value represents difference between subgroups: 1—survivors vs. nonsurvivors; 2—survivors vs. control; 3—nonsurvivors vs. control. The comparison of continuous variables between two independent groups (nonsurvivors vs. survivors) was performed using the Mann-Whitney test. The comparison of continuous variables across three groups (nonsurvivors, survivors, and control) was performed using the Kruskal-Wallis test, and a post hoc was used to compare subgroups. Plasma FN forms were revealed by SDS-agarose immunoblotting (see Figure 3(b)). Occurrence is the ratio of the number of samples containing the FN form to the total number of samples. The relative amount of the FN band is the percentage of the total number of pixels found in the electrophoresis path.
