Figure 2 Acetylcholine-induced dose-response curves for forearm blood flow (FBF) calculated as the percent increase in FBF from baseline in patients with C-reactive protein (CRP) less than the median value (triangles) and patients with CRP greater than or equal to the median value (circles). Solid symbols represent patients with IL-10 serum levels less than the median, and open symbols represent patients with IL-10 serum levels greater than or equal to the median. Data are expressed as the mean value ± SEM.
