  • 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.

  • Effect estimate.
