Figure 2. Mean change from baseline in central systolic blood pressure on (A) Day 1 and (B) Day 7 and in brachial systolic blood pressure on (C) Day 1 and (D) Day 7 after a high-nitrate or low-nitrate intervention in 27 healthy participants. Values are expressed as mean ± SEM. Different symbols denote a significant effect of high-nitrate compared to low-nitrate intervention as assessed by repeated measures ANOVA. ^*p = 0.004; ^†p = 0.025; ^‡p = 0.022.
