Comparison of the differences between the two groups of IL-17 and IL-1 before and after treatment (x̅±s)

	Group	Number of samples	Difference before and after treatment	t	P	95% CI of difference
IL-17 (ng/L)	Zhuanggu Zhitong Recipe Group	46	23.23±3.96	0.852	0.396	-1.065~2.664
	Alendronate sodium group	45	22.32±4.65
IL-1 (ng/L)	Zhuanggu Zhitong Recipe Group	46	13.52±0.66	0.019	0.985	-0.292~0.297
	Alendronate sodium group	45	13.51±0.74

Note: For IL-17, the difference 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 0.108 and 0.404 respectively, both of which were greater than 0.05, satisfying normality and having homogeneous variances. The homogeneity test L(1,89)=2.464, P=0.120, meets the homogeneity of variances, and uses the independent sample T test. For IL-1, the difference 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 0.224 and 0.623 respectively, both of which were greater than 0.05, satisfying normality and homogeneity of variance. The test L(1,89)=1.129, P=0.291, met the homogeneity of variances, and the independent sample T test was used.
