Distribution of Androgen Receptor expression among other molecular marker subsets^*. Association of Characteristics with AR level for all samples with AR level (n=134)

Characteristic	AR Level				p-value
	1	2	3	4
ER/PR
Positive	3 (13.0)	10 (43.5)	8 (34.8)	2 (8.7)	<0.0001
Negative	65 (73.9)	9 (10.2)	12 (13.6)	2 (2.3)
Triple Negative
Yes	61 (76.3)	8 (10.0)	9 (11.3)	2 (2.5)	<0.0001
No	14 (25.9)	15 (27.8)	19 (35.2)	6 (11.1)
ALDH1
Positive	29 (48.3)	12 (20.0)	14 (23.3)	5 (8.3)	0.40
Negative	46 (62.2)	11 (14.9)	14 (18.9)	3 (4.1)

AR level 1= AR negative

AR level 2= AR weakly positive

AR level 3= AR moderately positive

AR level 4= AR strongly positive

^*Significant difference in AR level for ER/PR positive vs. ER/PR negative – most ER/PR negative have no AR level, whereas most ER/PR positive have weak-strong AR levels Significant difference in AR levels for Triple Negative vs. not TN-most TN tumors have no AR levels whereas most none-TN tumors have weak-strong AR levels

ALDH positivity distribution does not differ significantly between AR levels
