However, several randomized controlled trials demonstrated that stricter control of HbA1c did not necessarily improve their cardiovascular outcomes (3-5). In particular, intensive lowering HbA1c elevates a risk of hypoglycemia which has been shown to associate with higher mortality (5). These observations suggest the limitation of HbA1c-based glycemic control for the prevention of diabetic macrovascular diseases. Given that HbA1c reflects average blood glucose in the past 1¨C2 months but not serial changes in glucose level including hypoglycemia, the another approach enabling real-time accurate monitoring of glucose level is required %U http://cdt.amegroups.com/article/view/29691/26109
