  1. L-EAA leucine-enriched essential amino acid, IQR interquartile range, BMI body mass index, APACHE II Acute Physiology and Chronic Health Evaluation II, TBI traumatic brain injury, ICU Intensive Care Unit, LOS length of stay
  2. Continuous variables shown as median (95% confidence intervals); categorical variables shown as frequencies (%)
  3. aHigher APACHE I scores indicate greater disease severity and correspond with risk of death
  4. bInjury Severity Score > 15 is defined as major trauma
