Table II.
Non-parametric analysis of the significance of the differences in MC detection performance of the three CADe systems, CADDBT, CADPPJ and CADDM, for the test set where the FP rates were estimated from views with MCs. The operating threshold was set at 1 FP/view for the analysis. The figure-of-merit (FOM) is the difference in the areas under the two FROC curves being compared, CI: 95% confidence interval.
