Mechanism of injury in patients with iTBI stratified by INR (n = 44)

Injury Mechanisms	INR <1.2 (n = 35)	INR ≥1.2 (n = 9)
High-velocity trauma, n (%)	6 (17)	4 (44)
Blow to head (direct impact), n (%)	5 (14)	NA
Head against object (direct impact), n (%)	2 (5.7)	1 (11)
Ground-level fall, n (%)	12 (34)	2 (22)
Fall from height (>1 m), n (%)	8 (23)	1 (11)
Other closed head injury, n (%)	2 (5.7)	1 (11)

Data on mechanism of injury were missing for n = 44 patients with iTBI.

INR international normalized ratio, iTBI isolated traumatic brain injury, NA not available.
