  1. TITA is the angle between two lateral tangential lines along the lateral borders of each vertebrae was also measured from posterior-anterior axis
  2. Positive value defined as convergence, and negative value defined as divergence from posterior-to-anterior axis
  3. Van Schaik et al. revealed his results in L3 to L5 only without L1 and L2 results provided
  4. * meant statistically significant between Caucasian and Taiwanese populations
