Table 1 Age, severity, LOS, IPPV days Mean values for age and SAPS II and median values for *LOS and **IPPV days (hours/24). Comparison of medical and surgical ICU patients, and of ICU patients with increasing and patients with decreasing summarized SF-36 scores from 6 months to 2 years after ICU discharge. Differences between the groups are shown with corresponding 95% confidence intervals (CI) or p-values (the Mann-Whitney test).
