Flow-mediated dilation and endothelial dysfunction by cardiovascular risk factors stratified by gender and metabolic syndrome.

Data are presented as mean with 95% Confidence interval (CI). n: number of participants fulfilling the specific criteria; No MetSyn: participants not fulfilling the specific criteriafor metabolic syndrome; MetSyn: participants fulfilling the specific criteria for metabolic syndrome; ED: endothelial dysfunction (FMD≤0%); FMD: flow-mediated dilation, as percent dilation from baseline diameter; FMDadj: FMD adjusted for age; HDL: high density lipoprotein. Annotations with letters on different FMD groups to indicate p-values for differences as follows (only significant differences listed): a different from b, c and d, p<0.001; e different from f and g and h, p<0.001; i different from j, p = 0.001; i different from l, p = 0.013; j different from k, p = 0.045; l different from m, p = 0.002; m different from o and p, p<0.001; m different from n, p = 0.002; q different from r, p = 0.007; v different from w, p = 0.028; v different from x, p = 0.040.
