Figure 1 Comparison of flow-mediated dilation (FMD) of the brachial artery at coronary stenting (Initial) and at the six-month follow-up (Follow-up) between patients with (n = 46) and without (n = 95) in-stent restenosis (ISR). The control subjects (n = 48) with normal coronary angiograms were selected to match age and gender of the patients with stenting and served as comparison of FMD with the patients. Data are expressed as mean ± SE. *p < 0.01 versus initial FMD in patients without ISR;  p < 0.01 versus control subjects.
