  • Note:—NA indicates not applicable; PTT, 2-tailed paired t test; WSR, Wilcoxon signed rank test.
  • ↵a Structures evaluated in the region of metal fixation hardware included the central canal, spinal cord, neural foramina, and prevertebral soft tissues.
  • ↵b A subgroup analysis of thoracic spine cases was not performed due to the few cases in this group.
