External Validation (Dataset 1) Receiver Operating Characteristic Curves and AUC Analysis for the SP A1 Parameter, CBI, and TBI Using Naive Bayes Classifier and for the Processed Pseudoimages Using DenseNet 121

Parameter (Pairwise Comparison)	Mean Δ AUC ± SE	95% CI	Z Statistic	P Value
SP A1 and DenseNet121	0.020 ± 0.024	0.0432, 0.0832	0.83	0.198
CBI and DenseNet121	0.048 ± 0.021	0.0020, 0.0980	2.28	0.013
TBI and DenseNet121	0.066 ± 0.026	0.0211, 0.1108	2.53	0.006
SP A1 and CBI	0.028 ± 0.013	0.0130, 0.0690	2.15	0.016
SP A1 and TBI	0.046 ± 0.020	0.0115, 0.0804	2.30	0.009
CBI and TBI	0.018 ± 0.010	0.0007, 0.0352	2.00	0.021

Δ AUC = difference between the area under the curve; CBI = Corvis biomechanical index; CI = confidence interval; ROC = receiver operating characteristic; SE = standard error; SP A1 = stiffness parameter at first applanation; TBI = tomography and biomechanical index.

The bold type signifies P ≤ 0.05.
