Figure 4

Kaplan-Meier survival curves for patients with metastatic spinal tumors treated by minimally invasive spine stabilization in group A (ESCCS 0, 1, 2) and group B (ESCCS 3). The median survival time was 12.0 months (95% confidence interval: 9.1-14.8) in group A and 15.0 months (95% confidence interval: 3.9–26.0) in group B, with no significant difference between the two groups (P=0.60).
