  1. * The diameter was measured at the widest point of the syrinx in transverse sections of MRI scans
  2. ** The syrinx lateralization was registered for the widest diameter of the largest syrinx in the cervical region (if more than one syrinx was present). A central syrinx was circular and situated centrally in the spinal cord, whereas a unilateral syrinx was asymmetrical and extended into one dorsal horn only. A bilateral syrinx extended into both dorsal horns
  3. IQR: interquartile ranges; Min: Minimum; Max: Maximum; n: number of dogs
