Evaluation of Rhubarb Supplementation in Stages 3 and 4 of Chronic Kidney Disease: A Randomized Clinical Trial

Table 1

Blood pressure in control and Rhubarb groups before and after 12 weeks of treatment.

Serial number	Parameter	Group	0 week; mean ± SD	12 weeks; mean ± SD	% change after 12 weeks	95% confidence interval
1	SBP (mm Hg)	I	150.40 ± 17.62	136.62 ± 16.45^b	(−) 9.16%	22.81 to 32.90
		II	152.97 ± 20.60	132.60 ± 8.79^b1	(−) 13.31%	31.93 to 44.30
2	DBP (mm Hg)	I	87.32 ± 10.43	85.98 ± 9.65	(−) 1.53%	12.43 to 22.92
		II	88.02 ± 12.40	84.73 ± 9.31^b1	(−) 4.40%	12.97 to 23.30

Values are mean ± SD; was considered significant; ^b compared to 0 week value of respective group; ¹ compared to control group. I: Control; II: Rhubarb; SBP: Systolic blood pressure; DBP: Diastolic blood pressure; (−) decrease.
