APACHE - Acute Physiology and Chronic Health Evaluation; ICU - intensive care unit; TBI - traumatic brain injury; ARDS - acute respiratory distress syndrome. Summary statistics of continuous variables are presented as the median (interquartile range), with p-values based on the nonparametric test (i.e., Wilcoxon rank-sum test). Summary statistics of categorical variables are presented as percentages, with p-values based on Pearson's Chi-squared test.
