| Odds ratio | 95% C.I. | p-value | |
|---|---|---|---|
| Time to receipt of first cooler (min) | 1.05 | 1.01–1.09 | 0.016 |
| Anatomic injury severity (ISS) | 1.05 | 1.03–1.06 | <0.001 |
| Disturbed arrival physiology (w-RTS) | 0.61 | 0.53–0.69 | <0.001 |
| Randomization group (1:1:2) | 1.46 | 0.92–2.29 | 0.102 |
| Resuscitation Intensity (units) | 1.03 | 0.60–1.44 | 0.184 |
