	RMSE Hepatic-IRbasal	CVPE Hepatic-IRbasal	RMSE Hepatic-IRclamp	CVPE Hepatic-IRclamp	RMSE Muscle-ISclamp	CVPE Muscle-ISclamp
HIRI	0.20	0.20	0.37	0.37	0.48	0.48
MISI	0.21	0.21	0.39	0.39	0.54	0.54
P value	0.96	1.00	0.95	1.00	0.99	0.48

CVPE and RMSE were calculated from calibration analysis of tissue-specific surrogate indices of insulin sensitivity derived from an OGTT as described in the research design and methods. P values correspond to comparisons between the surrogate indexes.
