Use of a Radiomics Model to Predict Tumor Invasiveness of Pulmonary Adenocarcinomas Appearing as Pulmonary Ground-Glass Nodules

Table 3

Multivariate analysis for differentiating preinvasive lesions from IPAs.

Feature	P value
PM	7.75E-06
Lobulated sign	0.046571
Pleural retraction	0.002485
Age	0.021143
FD	1.10E-14

Note: IPAs=invasive pulmonary adenocarcinomas, PM=pure or mixed density, and FD=fractal dimension.
