  2. ICU intensive care unit, OpR operating room, SD standard deviation, TBSA total body surface area, US United States
  3. Variables, such as TBSA, inhalation injury, ICU stay, and the need for surgery, show how much more severe the injuries were in those patients who ultimately died after their burns
