Comparison of the difference in TCM syndrome scores 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
Zhuanggu Zhitong Recipe Group	46	10.60±1.71	3.20	0.002	0.484~2.066
Alendronate sodium group	45	9.33±2.06

Note: A normality test was conducted on the difference between the two groups of TCM syndrome scores before and after therapy. The results were 0.095 and 0.084 respectively, which satisfied normality. The homogeneity of variance test L(1,89)=2.578, P=0.112, homogeneity of variances, using independent samples T test.
