Predictive models of significant injury, transfusion, and Injury Severity Score ≥16 in our cohort based on the stepwise logistic regressions that were performed

Models	OR	95% CI
Model for injury
Prehospital hypotension	0.40	0.19 to 0.81
Prehospital SI >1	2.01	1.02 to 3.98
Age	0.98	0.97 to 0.99
Penetrating trauma	0.31	0.15 to 0.62
Alcohol use	0.48	0.26 to 0.88
Model for transfusion
Prehospital hypotension	0.28	0.13 to 0.63
Prehospital SI >1	5.14	2.49 to 10.60
Age	1.01	1.01 to 1.03
ED hypotension	3.84	2.14 to 6.89
Model for ISS ≥16
Prehospital hypotension	0.28	0.13 to 0.60
Prehospital SI >1	3.10	1.53 to 6.25
Male gender	1.93	1.19 to 3.12
Penetrating trauma	0.24	0.11 to 0.48
ED hypotension	1.87	1.07 to 3.27
