Multivariate analysis for complete response (CR)
| Variables | Odds ratio | (95% CI) | p value |
|---|---|---|---|
| N stage: N1 vs N0 | 0.041 | 0.034-1.138 | 0.067 |
| Clinical Stage: 2 vs 3/4 | 6.864 | 0.541-9.354 | 0.193 |
| Circumferential extent: 60%> vs 60% < | 0.560 | 0.396-1.338 | 0.332 |
| CRT vs RT | 2.313 | 0.855-2.887 | 0.156 |
| Lymphocytes(%): 25.7% ≤ vs 25.7% > | 4.000 | 1.057-4.455 | 0.032 |
Five variables, N stage, Clinical stage, chemotherapy, circumferential extent, % lymphocytes which may have possible correlation with CR rate and their independency were analyzed with stepwise logistic regression analysis using JMP software 8.0.
