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)
