High-resolution computed tomography findings independently predict epidermal growth factor receptor mutation status in ground-glass nodular lung adenocarcinoma

Table 4 Area under the receiver operating characteristic curve of the models

Model	AUC	SE	95%CI	P value
Nodule size	0.625	0.061	0.504–0.745	0.048a
Nodule size + vacuole/honeycomb sign	0.698	0.055	0.589–0.806	0.002a

^aP < 0.05 is statistically significant.

ROC: receiver operating characteristic; AUC: area under the curve; SE: standard error; CI: confidence interval.
