Note:—SAH indicates subarachnoid hemorrhage; TBI, traumatic brain injury; HS, hemorrhagic stroke; IS, ischemic stroke; GW, gunshot wound; ISk, intact skull; BD, brain death; -, no data.
↵a Data are presented as No. (%), except for age (mean ± SD) and time (median and quartile). P values are for comparison of the subgroups (ISk, craniotomy, and craniectomy).
