Table 4. Cox proportional hazards analysis for overall survival rate.
Covariate | HR | 95% CI | P value |
---|---|---|---|
CCI | 19.613 | 5.353–71.865 | < 0.001 |
No. of spinal metastasis | 2.244 | 1.048–4.233 | 0.044 |
Corpectomy | 0.715 | 0.451–0.880 | 0.022 |
Spondylectomy | 0.619 | 0.021–0.822 | 0.015 |
Time to metastasisa | 0.487 | 0.128–0.826 | 0.045 |
Postop. chemotherapy | 0.455 | 0.031–0.708 | 0.031 |
A P value of < 0.05 was considered to indicate statistical significance. The boldface type indicates statistical significance.
HR = hazard ratio, CI = confidence interval, CCI = Charlson comorbidity index, Postop = postoperative.
