Correlation of proliferation or apoptosis indexes 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.
