Multivariate analysis for DMFS and PFS in patients with NPC (n=222)
| Endpoint | Variable | HR | 95% CI | P-value |
|---|---|---|---|---|
| DMFS | Clinical stage | 2.873 | 1.378–5.988 | 0.005 |
| CXCL12 rs1801157 | 3.332 | 1.597–6.949 | 0.001 | |
| PFS | Clinical stage | 1.806 | 1.033–3.158 | 0.038 |
| CXCL12 rs1801157 | 2.665 | 1.387–5.119 | 0.003 |
Note: P<0.05 was considered statistically significant.
