Multivariable model estimates for Local Failure and Postoperative LMD risk
| Local Failure Risk | HR | LCL | UCL | P-value | |
|---|---|---|---|---|---|
| Metastases | > 1 vs. Single | 2.65 | 1.07 | 6.59 | 0.0360 |
| Diameter of Index Tumor | > 3cm vs. ≤ 3cm | 4.16 | 0.96 | 18.02 | 0.0566 |
| Leptomeningeal disease Risk | HR | LCL | UCL | P-value | |
|---|---|---|---|---|---|
| Metastases | > 1 vs. Single | 2.07 | 0.98 | 4.36 | 0.0573 |
| Surgery to Radiosurgery | > 30 days vs. ≤ 30 days | 0.59 | 0.28 | 1.21 | 0.1477 |
| Cancer Type | Breast vs. Other | 2.37 | 0.93 | 6.07 | 0.0716 |
HR-Hazard Ratio; LCL=95% lower confidence limit; UCL-95% upper confidence limit; Multivariable models were based on a priori knowledge and stepwise selection criterion
