Correlation of difference of proliferation or apoptosis indexes between convex and concave side with various radiographic measurements expressed as Pearson or Spearmen correlation coefficients with significance set at P < 0.05. * Statistical significance.

AVT = Apex vertical translation; AVR = Apex vertebral rotation; DWA = Disc wedging angle of apex.
