Table 3 Multivariate analysis for prediction of mortality

From: Ultrasound measurements versus invasive intracranial pressure measurement method in patients with brain injury: a retrospective study

Characteristics p-value
Data of patients included in the analysis 47
Intracranial pressurea 0.015
Arterial blood pressure 0.12
Cerebral perfusion pressure 0.072
Partial pressure of carbon dioxide 0.085
Straight sinus systolic flow velocity 0.062
Straight sinus diastolic flow velocity 0.067
Straight sinus means flow velocity 0.068
Middle cerebral artery systolic flow velocity 0.078
Middle cerebral artery diastolic flow velocity 0.086
Middle cerebral artery means flow velocity 0.082
Optic nerve sheath diametera 0.035
Middle cerebral artery pulsatility index 0.095
  1. A p value less than 0.05 was considered significant
  2. Data of survived patients were considered as the reference standard
  3. aSignificant predictor of mortality
