Difference in Area Under the Receiver Operating Characteristic Curve and 95% Confidence Interval for Comparisons of Classification Protocols

Classification Protocol Comparison ΔAUC 95% Confidence Interval of the Difference P Value Statistical Conclusion
Signature based on feature selection on all features compared to maximum linear size −0.049 (−0.081 to −0.018) .005 Superior
Signature based on feature selection on all features excluding size compared to maximum linear size −0.050 (−0.080 to −0.024) .003 Superior
Signature based on feature selection on all features excluding size compared to that on all features −0.002 (−0.013 to 0.008) .664 Equivalent

AUC, area under the receiver operating characteristic curve.

P values shown are after correction for multiple comparisons.

Statistical conclusion was based upon superiority and equivalence testing.
