Table 8. Association between GRB7 expression (low/high) and location (cytoplasm/membrane) in 225 patients with invasive ductal carcinoma of the breast.

Categories		GRB7 location
		Cyto	Cyto + Memb	Total	p-value
GRB7 Expression	Low (1+)	94 (55.62)	3 (5.36)	97	<0.0001
	High (2+ – 3+)	75 (44.38)	53 (94.64)	128
	total	169	56	225

Cyto = cytoplasm alone, Cyto + memb = cytoplasmic with membrane accentuation.
