  • WMD is calculated as change in kyphoplasty minus change in vertebroplasty. Positive WMD means improvement was greater for kyphoplasty compared with vertebroplasty, except for kyphotic angle in which a negative value means improvement was greater for kyphoplasty compared with vertebroplasty.

  • WMD, weighted mean difference.
