      Major extracranial injury (MEI) is frequently present in patients with traumatic brain in-jury (TBI). The prevalence differs from 23%(1) to 41%(2) dependent on study population and definition of MEI. Relatively few studies have however focused on the effect of MEI on mortality after TBI. Most studies concerning TBI and MEI have investigated ...
