S I (10-4 dL·kg-1·min-1 /(μU·mL-1)), whole-body insulin sensitivity; Φ 1((pmol/L C-peptide)/(mmol/L glucose)), first-phase responsiveness index; Φ 2 (10-1 min-2·(pmol/L C-peptide)/(mmol/L glucose)), second-phase responsiveness index; Φ ss (min-1·(pmol/L C-peptide)/(mmol/L glucose)), steady-state responsiveness index. All the parameters and indexes were estimated or computed by CPMM and IVGTT, except for S I, which was estimated by GKMM and IVGTT. The percent coefficient of variation of the estimates (CV%) was given in parentheses, when available.
