  • Note.—AP indicates anteroposterior; CI, confidence interval; SAS, subarachnoid space.

  • * Patient 4 underwent only conventional radiography, and patient 5 underwent MR imaging of only the head; thus, they are not included.

  • Ratio between the anteroposterior diameter of the canal and the vertebral body.
