Group	ER stroma, points	ER gland, points	PR stroma, points	PR gland, points
I (n = 25)	45.2 ± 4.9	70.3 ± 7.6	150.7 ± 16.4	84.5 ± 9.2
II (n = 30)	92.2 ± 10.0*^,**	75.2 ± 8.2**	100.0 ± 10.9*^,**	73.2 ± 8.0**
III (n = 40)	75.5 ± 8.2	47.4 ± 5.2	167.7 ± 18.2	95.4 ± 10.3

*The outcome difference between the groups compared true with р < 0.05.
