Table 2.

Mass region based comparison of the total number of mass regions cued by changing the scoring projection line slopes including the number of cued regions with original CAD-generated scores (S_org) greater than the cueing threshold (T) and the number of cued regions with S_org < T at a false-positive rate of 0.25 per image.
