From: Is additional balloon Kyphoplasty safe and effective for acute thoracolumbar burst fracture?
Comparisons of the kyphoplasty and vertebroplasty in anterior vertebral height (a), kyphotic angle (b), mean VAS (c) and ODI (d) at baseline and follow-up. Group calculated means and 95% confidence intervals are shown in panels A, B, C and D. In panels A and B, the treatment p value refers to the average treatment effect difference (*, p < 0.05) at 3, 6, 12, and 24 months follow-up. In panels C and D, no clinical treatment effect difference was found at pre-operative and post-operative follow-up
