Table 3 Intra – and inter- observer reliability of the two evaluations of initial CT (MLS: midline shift, TH: thickness hematoma) In the second through last column 1, 2 respectively 3 mm were added to TH
From: Midline shift in relation to thickness of traumatic acute subdural hematoma predicts mortality
