Glucose and insulin levels at each time point during a cookie test in the control, acarbose and nateglinide groups. Plasma glucose and insulin levels were not changed at any time point in the controls after 12 weeks. Plasma glucose levels at 30 min during the cookie test were significantly decreased after 12 weeks of treatment with acarbose. Plasma insulin levels at 30 and 60 min were significantly increased after 12 weeks of nateglinide treatment.
