Figure 1 Forearm blood flow (FBF) dose–response curves to norepinephrine (NE, upper panel), angiotensin II (ANG II, middle panel), and vasopressin (VP, lower panel) at baseline and after administration of LPS (closed symbols) or placebo (open symbols). The response to vasoconstrictors was attenuated after LPS. The FBF ratio (intervention vs. control arm, baseline defined as 100%) is expressed as mean ± SEM. n = 9; *p < 0.05 between groups, repeated measures ANOVA and Bonferroni corrected t tests.
