Statistical evaluation of the DNN mitotic classifier in distinguishinging different breast cancer ODX risk groups: high ODX risk group (H), low ODX risk group (L), and intermediate ODX risk group (I)

RISK GROUP COMPARISON	P-VALUES (EQUALVARIANCE)
H vs. L	0.1×10−3
H vs. L and I	3.6×10−3
H and I vs. L	2.3×10−3
HH vs. LL	0.2×10−3
LL vs. rest of BCa cases (LLc)	0.032
HH vs. rest of BCa cases (HHc)	0.6×10−3

Additionally, the Bloom Richardson grading scheme was also used to define the high ODX-high grade group (HH) and the low ODX-low grade group (LL). Note that statistically significant differences were observed for all the six comparative experiments performed.
