TABLE 4.

Difference between premenopausal (time 1) and postmenopausal time (time 2) of the normal group, depression group and anxiety group.

			Mean Difference	Std.		95% Confidence interval
Group	(I) time	(J) time	(I-J)	Error	Sig.	for difference
						Lower bound	Upper bound
Normal group	1	2	0.070∗	0.028	0.014∗	0.015	0.125
	2	1	−0.070∗	0.028	0.014∗	–0.125	–0.015
Anxiety group	1	2	0.178∗	0.043	0.000∗∗∗	0.092	0.263
	2	1	−0.178∗	0.043	0.000∗∗∗	–0.263	–0.092
Depression group	1	2	0.276∗	0.054	0.000∗∗∗	0.169	0.383
	2	1	−0.276∗	0.054	0.000∗∗∗	–0.383	–0.169

The simple effect shows that there are differences between the two time points in the normal group, there are differences between the two time points of the anxiety group, and there are also differences between the two time points in the depression group. ^∗P < 0.05; ^∗∗∗P < 0.001.
