  • Quantitative variables are expressed as median and 25th–75th percentiles interval.

  • *Admission pupillary changes data were missed in three patients.

  • †Haematoma site in supratentorial location data were missed in 2 of 263 patients with supratentorial origin of the haematoma. Calculations were made regarding these 261 patients.

  • APACHE-II, Acute Physiology and Chronic Health Evaluation II; GCS, Glasgow Coma Scale; ICH, intracerebral haemorrhage; ICU, intensive care unit.
