Data are expressed as mean (range) unless indicated otherwise.
The number of data points for each clinical variable are: ISS and NISS, n = 48; AIS scores, n = 50; ICU and hospital free days, n = 53.
ICU-free days and hospital-free days were calculated by 30 minus the number of days the patient stayed in hospital).
A/P, Assault/penetrating; AIS, Abbreviated injury scale; ISS, Injury severity score; ICU, Intensive care unit; NISS, New injury severity score; RTC, Road traffic collision.
