  • CVPE and RMSE were calculated from calibration analysis of various surrogate indexes of insulin sensitivity as described in research design and methods based on 78 subjects who underwent both glucose clamp and FSIVGTT studies. P values correspond to comparisons between QUICKI and alternative surrogate indexes.
