Population	Genotype Means (95% C.I.)** of Insulin Sensitivity in mg/kg/min			p-value†
All	CC= 10.9 (10.6, 11.3) N = 314	CT= 11.1 (10.4, 11.7) N = 205	TT= 11.1 (9.9, 12.2) N = 40	.85
Whites	CC= 11.1 (10.6, 11.5) N = 262	CT= 11.1 (10.5, 11.7) N = 175	TT= 11.8 (10.6, 13.0) N = 33	.48
African Americans	CC= 10.1 (9.2, 11.0) N = 52	CT/TT= 10.7 (9.4, 12.0) N = 37		.40††
Parents (ages 32-64, median = 48)	CC= 11.1 (10.4, 11.8) N = 117	CT= 11.4 (10.6, 12.3) N = 81	TT= 11.7 (9.6, 13.8) N = 14	.75

^*All regression analyses adjusted for age and sex

^†for a 2 d.f. test, except in African Americans

^††where CT and TT genotypes were combined for analysis due to small numbers resulting in a 1 degree of freedom test
