  1. Note: PVWCD represents the depth of the concave posterior vertebral wall. VBSD represents the Mid-sagittal diameter of the non-fracture vertebral body. Mark -- indicates that the value was almost 0 and could not be accurately measured by CT
  2. *Compared with the thoracic vertebral group, P < 0.05
