% SDH SM – proportion of dogs that had a syrinx which extended to superficial dorsal horn
# SDH SM - number of dogs that had a syrinx which extended to superficial dorsal horn
#SM - number of dogs that had a syrinx at that spinal cord segment. Bold font - p values indicates a significant result (p < 0.05)
