	Number	Wnt7a expression		P*-value
		Negative (%)	Positive (%)
Proliferative endometrium	12	2 (16.7)	10 (83.3)	0.004
Secretory endometrium	13	1 (7.7)	12 (92.3)	<0.001
Atrophic endometrium	10	1 (10.0)	9 (90.0)	0.002
Simple hyperplasia	16	3 (18.8)	13 (81.2)	0.002
Complex hyperplasia	17	4 (23.5)	13 (76.5)	0.004
Endometrial carcinoma	70	44 (62.9)	26 (37.1)

Proliferative endometrium versus carcinoma: 0.004; Secretory endometrium versus carcinoma: <0.001; Atrophic endometrium versus carcinoma: 0.002; Simple hyperplasia versus carcinoma: 0.002; Complex hyperplasia versus carcinoma: 0.004 and *Chi-square test.
