18F-FDG-PET/CT-based machine learning model evaluates indeterminate adrenal nodules in patients with extra-adrenal malignancies

Table 4 The comparison of the AUCs between the predictive model and individual risk factors

Comparison	AUC	Z statistic	P
Predictive model vs gender	0.936 vs 0.656	8.170	< 0.001
Predictive model vs CTU	0.936 vs 0.788	4.810	< 0.001
Predictive model vs SUV/liver	0.936 vs 0.851	3.754	< 0.001

AUC area under the receiver operating characteristic curve, CTU the value on unenhanced CT, SUV/liver the ratio of the adrenal, SUVmax to the mean liver SUV
