  1. OVF osteoporotic vertebral fracture, wedge-type OVF OVF with reduced anterior vertebral height, flat-type OVF OVF with reduced anterior, middle, and posterior vertebral heights by > 20% of the average values for the adjacent cranial and caudal vertebrae [24]
  2. #These dimensions were measured on radiographs taken in the sitting position
  3. LLocal kyphosis angle was measured in 44 OVFs after excluding radiographs with low quality
  4. Paired Student’s t-test
