Table 1.

Image features discriminating grading groups.

Field^a	Image features	p-value^b	Correct classification^c
Field 1	Morphologic: minor ellipse axis	<0.001	65.0%
	Texture: sum entropy
Field 2	Morphologic: perimeter	<0.001	67.1%
	Texture: angular second moment
	Densitometric: range density
Both fields	Morphometric: minor ellipse axis	<0.001	65.0%
	Texture: peak transition probability

Field 1 and Field 2 each had 5 different ducts.

p-values are based on F-statistic of final discriminant models.

Jackknifed (leave-one-out) classification.
