Table 2.

Logistic regression model performed to ascertain the effects of GCS score, age, gender, ISS, penetrating vs blunt injury and method of transportation (HemS vs ground ambulance) on the likelihood of mortality

Variable	Odds	95% CI	P value
Helicopter transport	0.43	0.41 to 0.44	<0.0001
GCS score	0.95	0.94 to 0.95	<0.0001
Age	1.003	1.003 to 1.003	<0.0001
Male gender	1.014	0.45 to 2.3	0.973
ISS	1.002	1.002 to 1.002	<0.0001
Penetrating injury	2.5	1.918 to 2.939	<0.0001
