  1. CD chondrodystrophic, CI confidence interval, NCD Non-chondrodystrophic
  2. Statistically significant differences between the NCD and CD motion segments in both flexion and extension and axial rotation motions are observed, indicating that the CD motion segments incur greater displacement (decreased stiffness) than the NCD motion segments
  3. p < 0.05 was considered significant
