Figure 6 illustrates significant changes obtained for a number of atlantoaxial linear parameters based on the total sample of patients, including significant changes for Chamberlain by 0.93 mm ± 2.58 mm (p = 0.0055) and highly significant changes for CVT (p = 0.0003), OPT (p < 0.0001) and Redlund-Johnell/Petersson (p < 0.0001).
