Table II.

Changes in systolic BP measured over the 12-week treatment and 4-week post-treatment follow-up periods in prehypertensive and mildly hypertensive subjects.

	Prehypertensive		Mildly hypertensive
Time	Placebo group (n=17)	GH group (n=15)	Placebo group (n=21)	GH group (n=19)
Baseline	133.6±0.8	133.5±1.2	142.3±1.2	142.7±1.3
Week 4	129.4±1.6a	127.9±1.7a	141.2±1.9	137.7±2.2a
Week 8	129.7±2.0	131.0±1.7	140.9±1.9	135.2±1.5b
Week 12	131.7±1.4	129.9±2.1	141.6±1.6	136.1±1.8b
Post-week 4	128.9±1.6a	131.9±1.5	141.6±2.0	137.2±1.5b

Values are the mean ± standard error of the mean (SEM). Baseline values were determined immediately prior to the start of treatment.

^aP<0.05,

^bP<0.01 against baseline (within-group differences in measurement). GH, garlic homogenate-based supplementary diet; BP, blood pressure.
