*We adjusted for admission haematoma volume and admission Graeb Score.
†We adjusted for admission Graeb Score.
IVH, interventricular haemorrhage; NA, not assessed due to incomplete representation; NI, not included in the model due to insignificance or representation by other values (collinearity); SAH, subarachnoid hemorrhage.
