Effects of quercetin on systolic blood pressure measured by tail-cuff plethysmography in the four groups.

<p>The characteristics of the systolic blood pressures from week 1 to week 12 in the four groups are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0072548#pone-0072548-g002" target="_blank">Figure 2</a>. Each value represents the mean ± sem (n = 8 in each group). ^*<i>P</i><0.05, ^**<i>P</i><0.01, vs. the spontaneously hypertensive rats (SHR) group; <b>^#</b><i>P</i><0.05, vs. the SHR+QH group.
