Comparison of inflammatory factor levels between two groups before intervention, 6 and 12 months after intervention

Norm	Period of intervention	Groups	n	x ± s, points(95% CI)	t	P
IL-6(pg/mL)	Before intervention	Control group	104	18.55 ± 5.12	0.233	0.816

	Intervention for 6 months	Control group	104	14.82 ± 3.01*	2.826	0.005
		Research group	104	13.69 ± 2.75*
	Intervention for 12 months	Control group	104	13.06 ± 2.56*#	3.027	0.003
		Research group	104	12.06 ± 2.19*#
TNF-α(ng/L)	Before intervention	Control group	104	157.59 ± 12.37	0.346	0.730
		Research group	104	158.19 ± 12.62
	Intervention for 6 months	Control group	104	86.44 ± 9.68*	8.858	0.000

Hs-CRP(mg/L)	Before intervention	Control group	104	8.59 ± 0.92	0.676	0.500
		Research group	104	8.67 ± 0.78
	Intervention for 6 months	Control group	104	6.71 ± 0.59*	10.814	0.000
		Research group	104	5.96 ± 0.39*
	Intervention for 12 months	Control group	104	4.62 ± 0.32*#	5.276	0.000
		Research group	104	3.48 ± 0.18*#

Note:# Compared with this group after 6 months of intervention, P < 0.05; IL-6: Interleukin-6; TNF- α: Tumor necrosis factor; * Compared with before intervention in this group, P < 0.05; Hs-CRP: Hypersensitivity C-reactive protein. A 95% CI indicates that there is a 95% probability that the estimate will fall within that interval in repeated sampling
