  1. LR+ = likelihood ratio for positive results, LR- = likelihood ratio for negative results. Quick Surgical Airway Assessment for Trauma (qSAT) score was defined as the total of the three component scores, including male sex (female, 0 point; male, 1 point), presence of the facial injury (no, 0 point; yes, 1 point), and presence of the cervical area injury (no, 0 point; yes, 1 point), for a total score ranging from 0 to 3
