Variation comparisons

F‐test comparing μd distributions P‐value	Full dataset (n = 199)	Different acquisition technique (n = 111)	Same acquisition technique (n = 88)
No correction vs thickness correction	<0.0001	<0.0001	0.0023
No correction vs both corrections	<0.0001	<0.0001	<0.0001

The variance from the right and left breast calibrated difference distributions were compared within each group. This table gives the P‐values from the F‐test. The noncorrected data were used as the reference.
