Comparison of accuracy between different types of cone-beam computed tomography setting mode with and without the metal artifact reduction (MAR) option

Setting type	Accuracy (AUC) difference	p-value
HIRes MAR ~ Standard MAR	0.045	0.018
HIRes MAR ~ Standard	0.040	0.106
HIRes ~ HIRes MAR	0.006	0.761
HIRes ~ Standard MAR	0.051	0.011
Standard MAR ~ Standard	0.006	0.819
HIRes ~ Standard	0.045	0.020

HIRes – high-resolution, AUC – area under the receiver operating characteristic curve
