Table 2
Cox proportional regression analyses of variables affecting the local recurrence-free survival (LRFS) in NPC patients.
| Variables | Subsets | Local recurrence-free survival | Univariate analysis | Multivariate analysis | HR (95% CI) | value | HR (95% CI) | value |
| HLA-F expression | High vs. low and moderate | 3.80 (1.43–10.11) | 0.008 | 3.87 (1.29–11.58) | 0.016 | Gender | Male vs. female | 0.41 (0.10–1.66) | 0.213 | | | Age (years) | <54 vs. ≥54 | 0.29 (0.06–1.46) | 0.133 | | | Tumour differentiation | Undifferentiated vs. differentiated | 2.01 (0.50–8.07) | 0.325 | | | Tumour stage | T1 + T2 vs. T3 + T4 | 5.36 (1.25–23.06) | 0.024 | 4.31 (1.01–18.46) | 0.049 | Lymph node status | N0 vs. N1–3 | 3.04 (0.37–24.72) | 0.299 | | | TNM stage | I + II vs. III + IV | 1.76 (0.35–8.75) | 0.490 | | |
