Contribution of insulin-stimulated glucose uptake and basal hepatic insulin sensitivity to surrogate measures of insulin sensitivity.
OBJECTIVE—The goal of this study was to evaluate the performance of surrogate measures of insulin sensitivity and insulin secretion. RESEARCH DESIGN AND METHODS—The homeostasis model assessment (HOMA) of insulin resistance (IR) and the insulin sensitivity index (Si) from oral glucose tolerance test (OGTT) were compared with the M value from a hyperinsulinemic-euglycemic clamp in 467 subjects with
