Efficacy and mortality/mortality rate within each treatment approach
| Efficacy Rate (%) (95% CI) | MM Rate (%) (95% CI) | |
| Natural history | 77 (95% CI 75 to 83) | 21 (95% CI 16 to 28) |
| Surgery | 97 (95% CI 95 to 99) | 11 (95% CI 9 to 12) |
| Radiosurgery | 86 (95% CI 81 to 90) | 9 (95% CI 7 to 12) |
The outcomes were measured by calculating the cumulative incidence with corresponding 95% CIs. The random effects model was used. For further details and illustrative forest plots, see online supplemental eFigure 5.
