Characteristic Sensitivity, % Specificity, % NPV, % PPV, % OR (95% CI) Az (95% CI)
3D C1 94.1 45.3 96.0 35.6 13.241 (1.635-107.209) 0.697 (0.569-0.825)
2D C1 94.1 41.5 95.7 34.0 11.355 (1.400-92.066) 0.678 (0.547-0.809)

NPV, negative predictive value; PPV, positive predictive value; OR, odds ratio; CI, confidence interval; Az, area under the curve; 3D, three-dimentional; C1, presence of contact; 2D, two-dimentional.
