TABLE 1

Clinical and metabolic characteristics of subjects divided into categories of normal (NFG) and impaired fasting glycemia (IFG), and subdivided according to glucose tolerance (normal glucose tolerance [NGT], impaired glucose tolerance [IGT], and diabetic glucose tolerance [DGT]); and subjects with type 2 diabetes according to fasting hyperglycemia (plasma glucose > 7.0 mmol/l).
