Data presented as median (interquartile range) or percentage, unless otherwise stated. ALI, acute lung injury; APACHE, Acute Physiology and Chronic Health Evaluation. aAPACHE II scores include points awarded for patient age. After removing these points, the median and interquartile range of scores for each age category are as follows: <40, 24 (20 to 33); 40 to 49, 23 (18 to 32); 50 to 59, 25 (18 to 31); 60 to 69, 22 (16 to 29); 70 to 79, 23 (15 to 30); ≥80, 23 (15 to 29). bProportions may not sum to 100% due to rounding. cAmong patients with a limitation in life support before ICU discharge or cardiac arrest.
