Comparison of AMPK content differences between the two groups before and after treatment (x̅±s)

	Group	Number of samples	Difference before and after treatment	t	P	95% CI of difference
AMPK (pg/mL)	Zhuanggu Zhitong Recipe Group	46	2.73±0.65	-0.939	0.350	-0.318-0.139
	Alendronate sodium group	45	2.85±0.60

Note: The difference in AMPK expression levels between the Zhuanggu Zhitong Recipe group and the alendronate sodium group before and after treatment was calculated respectively. A normality test was performed on the differences between the two groups. The results were 0.274 and 0.951 respectively, which satisfied the normality. The differences between the two groups were tested for homogeneity of variances, L(1,89)=0.357, P=0.552, which satisfied the homogeneity of variances, and the independent sample T test was used.
