Multivariate Analyses of Clinicopathologic and Imaging Variables on PFS
| Model A* | Model B* | |||
| Variable | Hazard ratio | P† | Hazard ratio | P† |
| Lymphovascular invasion, no vs. yes | 2.87 (0.49–16.69) | 0.239 | 2.23 (0.38–12.92) | 0.372 |
| Perineural invasion, no vs. yes | 1.01 (0.171–5.50) | 0.970 | 1.20 (0.21–6.97) | 0.839 |
| pT1–2 vs. pT3–4 | 1.10 (0.24–2.55) | 0.551 | 1.69 (0.36–4.60) | 0.872 |
| pN0 vs. pN1–2 | 1.27 (0.38–4.46) | 0.876 | 1.10 (0.25–4.61) | 0.922 |
| Overall pTNM stage I–II vs. III–IV | 1.91 (0.38–9.51) | 0.431 | 1.87 (0.67–10.10) | 0.186 |
| MTV ≤ 17.7 vs. > 17.7 mL | 11.50 (1.45–91.01) | 0.011 | — | |
| TLG ≤ 56.3 vs. > 56.3 g | — | 3.55 (1.07–11.76) | 0.038 | |
↵* Because of multicolinearity (r = 0.902) between MTV and TGA, TLG and MTV were not included in models A and B, respectively.
↵† Multivariate analysis using Cox-proportional hazards model. Variables with P < 0.05 in univariate analyses were selected for multivariate analysis.
