Reduction in SBP in subjects with mild to moderate hypertension, derived from a comparison of the BP values in Fig. 1 with the baseline values. Each point on the graph represents the average of at least 25 independent derivations. Error bars SEM. ***P < 0.001 (H. sabdariffa and lisinopril vs.placebo); ^αα P < 0.01, ^ααα P < 0.001 (H. sabdariffa vs. lisinopril). All analyses were performed with two-way ANOVA with the Bonferroni posttest using the GraphPad Prism 5.0 analysis program
