Univariate logistic regression analysis for discrimination of primary lung cancer from pulmonary metastases
| Variable | Coeffecient | [CI] | p value |
|---|---|---|---|
| IC | − 0.481 | [− 0.95, − 0.07] | 0.03 |
| Zeff | − 0.66 | [− 1.36, 0.13] | 0.09 |
| HU | 0.01 | [− 0.01, 0.02] | 0.25 |
CI indicates bootstrapped 95% confidence intervals (2000 replicates). IC, iodine concentration on dual-energy computed tomography; HU, conventional computed tomography attenuation values in Hounsfield units; Zeff, effective atomic number. Italic indicates significant p values (< 0.05)
