  1. aThe ICH score for risk stratification in intracerebral haemorrhage ranges from 0 to 6, composed of points assigned to the criteria GCS, age, ICH location, ICH volume, and presence of intraventricular blood was assessed in 12 patients
  2. bThe Marshall classification of traumatic brain injury is based on initial CT scan and ranges from I-VI
  3. cThe modified Fisher Scale is a method for radiological grading of SAH secondary to intracranial aneurysm rupture. It runs between 1 and 4
  4. BMI body mass index; GCS Glasgow Coma Scale; ICH intracerebral haemorrhage; TBI traumatic brain injury; SAH subarachnoid haemorrhage; ICP intracranial pressure; ICU intensive care unit
