All bolded p values are those <0.05 when comparing the variables between alive/dead and favorable/unfavorable outcome groups. favorable, Glasgow Outcome Scale of 5–8, unfavorable, Glasgow Outcome Scale of 1–4.
ICP, intracranial pressure; MAP, mean arterial blood pressure; PRx, pressure reactivity index (correlation between ICP and MAP), SD, standard deviation.
