  1. All subjects included in Study A (n = 63) with discharge samples and subjects with consequent post-ICU samples (n = 49), and subjects included in Study B with post-ICU samples (n = 92). Comparison of survivors and nonsurvivors was done in each group using the Mann-Whitney test. CI, confidence interval.
