Kaplan-Meier curves for cumulative event-free survival associated with endothelial function measured as flow-mediated dilatation (FMD) (lowest tertile<2%, highest tertile>6.3%). Log-rank analysis revealed a significant difference between the low and intermediate tertiles (p=0.037). Further analysis revealed a significant difference in event rate between those with the most severe FMD abnormality (tertile 1) and the combined group of second and third tertiles (log-rank p=0.029). When this analysis was restricted to all-cause mortality alone, it remained significant (log-rank p=0.047). Adapted from Fathi et al. (68).
