Table 2 Diffusion tensor tractography parameters of lower dorsal and upper ARAS of the subgroup A, B and control groups

From: The relationship between consciousness and the ascending reticular activating system in patients with traumatic brain injury

  Subgroup A Subgroup B Control group F P
Lower dorsal ARAS
 FA 0.68 (±0.12) a 0.77 (±0.06) b 0.81 (±0.02) b 7.10 < 0.05*
 TV 730.84 (±425.17) 950.08 (±412.12) 953.61 (±156.14) 0.69 0.20
Upper ARAS
 FA 0.60 (±0.05)a 0.69 (±0.04)b 0.72 (±0.03)b 39.16 < 0.05*
 TV 38,751.28 (±16,162.42) 47,132.42 (±9651.04) 47,267.00 (±7883.63)b 2.23 0.12
  1. Values represent mean (±standard deviation); ARAS Ascending reticular activating system, FA Fractional anisotropy, TV Tract volume; One-way ANOVA and the LSD post hoc test were used for comparison of diffusion tensor parameters
  2. *significant difference between the patient and control groups at the indicated p
  3. LSD test result: a < b
