Insulin homeostasis traits from the OGTT
| Trait | Definition |
|---|---|
| Insulin sensitivity index (ISI) | 10 000/square root of (Glu0 × Ins0 × Glumean × Insmean) |
| Insulin secretion | AUC-Ins30/AUC-Glu30 |
| Insulin clearance | AUC-Cpep/AUC-Ins |
Abbreviations: AUC, area under the curve; Cpep, C-peptide; Glu0, Ins0, fasting glucose, insulin; Glumean, Insmean, mean glucose and insulin concentrations during OGTT; G30, I30, 30 minute glucose, insulin.
