Comparison of differences between the two groups before and after treatment with L-NTX and TRACP-5b (χ±s)

	Group	Number of samples	Difference before and after treatment	t	P	95% CI of difference
L-NTX (nmolBCE/L)	Zhuanggu Zhitong Recipe Group	46	21.17±4.57	-2.71	0.008	-4.033~-0.623
	Alendronate sodium group	45	23.50±3.53
TRACP-5b (U/L)	Zhuanggu Zhitong Recipe Group	46	0.374±0.002	-31.98	0.001	-0.019~-0.017
	Alendronate sodium group	45	0.392±0.002

Note: L-NTX content between the two groups before and after treatment was calculated separately, and the normality test was performed on the difference between the two groups. The results were 0.353 and 0.142 respectively, both greater than 0.05, which satisfied normality and having homogeneous variances. The results of the homogeneity test: L(1,89)=1.252, P=0.266, satisfying the homogeneity of variances, using the independent sample T test. TRACP-5b content between the two groups before and after remedy was calculated respectively, and the normality test was performed on the difference between the two groups. The results were 0.260 and 0.134 respectively, both greater than 0.05, satisfying normality and variance. Homogeneity test results: L(1,89)=0.024, P=0.876, which meets the homogeneity of variances and used the independent sample T test.
