Patients with moderate traumatic brain injury (mTBI) are 1,5 times more frequent than those with severe TBI and some of them will develop secondary neurologic deterioration (SND) within the first 7 days. However, identifying at risk patients of SND is still challenging. This study aimed to determine risk factors associated with SND after mTBI.
