Table 2.

Estrous cycle comparison among each group (χ²)

Group	n	Days –14-–1 Normal	Days 1-14					Days 15-28			Ratio of irregular cycle (%)
Group	n	Days –14-–1 Normal	Normal	Prolonged	Stagnate	No cycle	Normal	Prolonged	Stagnate	No cycle	Ratio of irregular cycle (%)
Blank	20	20^a	19	0	1	0	18	1	1	0	10
Model	20	20	1	6	3	10	5	7	5	3	75
BCD	20	20	2	8	1	9	17	2	0	1	15^b
EV	20	20	1	5	6	8	17	1	1	1	15

Notes: blank group: equal amount of normal saline, 14 d; model group: equal amount of normal saline, 14 d; BCD group: Bushen Culuan decoction, 18.35 g·kg^-1·d^-1, 14 d; EV group: estradiol valerate intervening group, 0.15 mg·kg^-1·d^-1, 14 d. ^aP < 0.05, compared with the other 3 groups; ^bP < 0.05, compared with model group.
