On univariate analysis in the conservative cohort, there were significant differences in age (p < 0.001), pre-injury mobility (p = 0.028), Hb (p = 0.038), and Alb levels (p = 0.011), ASIA Impairment Scale grade (p = 0.022), number of patients with cervical fracture (p = 0.025), and comorbid major organ injury (p = 0.006) between patients with and without delirium (Table 1). Here, ALB is linked to delirium.
