Multivariable logistic regression analysis for risk of venous thromboembolism and mortality in geriatric trauma patients with isolated traumatic brain injury (LMWH vs. UH) separated by AIS-head-grade
| Risk factor | OR | CI | p-value |
|---|---|---|---|
| AIS-Head Grade 3 | |||
| VTE | 0.83 | 0.52–1.32 | 0.423 |
| Mortality | 0.82 | 0.59–1.13 | 0.224 |
| AIS-Head Grade 4 | |||
| VTE | 0.64 | 0.40–1.02 | 0.059 |
| Mortality | 0.72 | 0.53–0.97 | 0.028 |
| AIS-Head Grade 5 | |||
| VTE | 0.94 | 0.62–1.43 | 0.761 |
| Mortality | 0.74 | 0.59–0.92 | 0.006 |
Controlled for hypotension on admission, blood transfusion, any surgical intervention, male sex, craniectomy/craniotomy within first 24-h, age ≥ 75-years-old, time to prophylaxis, injury severity score, Glasgow coma scale, and AIS-head grade
LMWH low-molecular-weight-heparin, UH unfractionated heparin, AIS abbreviated injury scale, VTE venous thromboembolism
