Figure 1 Plot of the mean flow-mediated dilation (FMD) of the brachial artery by mean Framingham risk estimate for each of the study populations. Line is the Lowess regression line. Points are weighted according to the inverse variance of FMD for each study [1/SE (FMD)2]. Tertiles of Framingham risk cutoff points were 2.8% and 9.5%.
