†Wilcoxon signed-rank test comparisons were made between admission and 6, 12, and 18 mo after ICU discharge.

‡Comparisons were made between admission and 6 and 12 mo after ICU. There was no significant difference of quality of life scores between 12 and 18 mo for BPA (P = 0.102) and ES (P = 0.063).
