Univariate and multivariate Logistic regression analysis
| Factors included | Univariate Logistic | Multivariate logistic | ||
|---|---|---|---|---|
| O^R | 95% CI | O^R | 95% CI | |
| Proximal to the major vessels | 1.724 | 1.020–2.912 | 1.599 | 0.869–2.940 |
| Centrally located lesions | 0.133 | 0.073–0.240 | 0.131 | 0.070–0.244 |
| Tumors size > 12.1 cm | 0.253 | 0.140–0.456 | 0.226 | 0.116–0.439 |
| Multiple tumors | 2.092 | 1.225–3.572 | 1.860 | 1.003–3.449 |
EN was taken as the experimental group and LR as the control group. Proximal to the major vessels, centrally located, tumor size > 12.1 cm and multiple tumors were taken as independent variables or exposure factors. OR was equal to the ratio of exposure to non-exposure in EN group divided by the ratio of exposure to non-exposure in LR group
