| Outcomes or subgroups | No. of studies | No. of patients | Statistical method | Effect estimate (95% CI)† | P value |
|---|---|---|---|---|---|
| (9) Adjacent new vertebral fractures | 7 | 667 | OR | 1.26 [0.69, 2.29] | >.05 |
| 9.1 at 6 months | 2 | 136 | OR | 0.14 [0.02, 1.21] | >.05 |
| 9.2 at 1 year | 5 | 531 | OR | 1.78 [0.91, 3.49] | >.05 |

| 10.1 to disc | 5 | 841 | OR | 2.10 [1.31, 3.37] | <.05* |
| 10.2 paravertebral | 5 | 675 | OR | 2.36 [1.27, 4.40] | <.05* |
| 10.3 total | 9 | 694 | OR | 2.15 [1.35, 3.44] | <.05* |
OR, Odds Ratio; CI, confidence interval.
If effect estimate is positive (> 0), it means vertebroplasty group is more than kyphoplasty group. If it is negative (< 0), it means vertebroplasty group is less than kyphoplasty group. Whether it is significant lies on P value.
↵* Statistically significant.
