Comparison of the mean changes in scores of systolic and diastolic blood pressure, pulse rate, and body mass index in the two groups before and immediately and one month after the intervention

Variable	Time	Study group	Control group	Repeated measures	ANOVA
		Mean ± SD	Mean ± SD	P*	P**
Systolic blood pressure	Before the intervention	144.4 ± 18.1	142.5 ± 15.2	0.027	< 0.001
	Immediately after the intervention	135.6 ± 13.7	140.9 ± 15.3
	One month after the intervention	131.7 ± 13.0	138.0 ± 15.0
Diastolic blood pressure	Before the intervention	84.3 ± 9.0	84.9 ± 10.7	0.040	0.015
	Immediately after the intervention	80.5 ± 6.5	83.3 ± 8.8
	One month after the intervention	78.9 ± 6.4	83.0 ± 7.3
Pulse rate	Before the intervention	81.9 ± 10.0	80.6 ± 7.3	0.900	0.899
	Immediately after the intervention	79.6 ± 4.6	81.8 ± 4.3
	One month after the intervention	80.9 ± 5.8	80.8 ± 3.8
BMI	Before the intervention	27.7 ± 3.2	28.7 ± 3.5	0.0340	0.010
	Immediately after the intervention	26.7 ± 3.2	28.9 ± 3.6
	One month after the intervention	26.6 ± 2.7	28.9 ± 3.6
