Figure 2From: Brachial artery reactivity in patients with severe sepsis: an observational studyBrachial artery reactivity in severe sepsis patients versus control subjects: hyperemic velocity (a) and flow-mediated dilation (b). Box plots show the median (horizontal line), 25th, and 75th percentiles (lower and upper limits of the box). The dots represent outliers beyond the whiskers that designate the 10th and 90th percentiles. Comparisons made with the Wilcoxon rank-sum test.Back to article page
