^*Comparison between patients staying in ICU ≥3 days and patients staying in ICU 0–2 days. Bold indicates P-values <0.05
^aValues are reported as median (range) or n (%)
^bAdmission GCS scores were not available in seven of the patients due to drug/alcohol intoxication giving false low GCS score (n = 112). Pre-intubation GCS scores were used for patients intubated at injury site (n = 15) or at local hospital (n = 16)
