Background: The shape of the glucose response curve during an oral glucose tolerance test (OGTT) can predict Beta-\ncell function and insulin resistance. However, there have been few studies conducted on Chinese people. Thus, we\naimed to verify the usefulness of the glucose response curve in a large Chinese population.\nMethods: A total of 9059 OGTT (3-h tests) were categorized into either a monophasic or a multiphasic group\nbased on the shape of the glucose response. Homeostasis model assessments of fasting insulin resistance, the\nMatsuda Index, the insulinogenic index, and the disposition index were assessed by plasma glucose and serum\ninsulin concentration obtained at fasting or during an OGTT.................................
