Clinical variables associated with increased 90-day mortality were a Glasgow Coma Scale (GCS) score &amp;lt;9 on arrival (adjusted odds ratio (aOR) 1.43; 95% confidence interval (CI) 1.03\u20131.98; P = 0.03) and systolic blood pressure =180 mmHg on arrival (aOR 1.39; 95%CI 1.05\u20131.83; P = 0.02).
