Comparison of the difference in waist pain NRS 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	2.42±0.71	4.68	0.019	0.365~0.922
Alendronate sodium group	45	1.76±0.61

Note: The normality test was performed on the difference in NRS scores of cold waist pain between the two groups before and after treatment. The results were 0.202 and 0.233 respectively, which satisfied the normality. The homogeneity of variance test L(1,89)=1.082, P=0.301, indicating homogeneous variances, using the independent sample T test.
