Area Under ROC Curve to Predict Development of Diabetes Within Groups of White and Black Participants

Predictors	White	Black
ARIC diabetes risk score	.68	.72
BMI, 3 categories	.63*	.69*
BMI, 3 categories plus family history of diabetes (siblings and parents)	.64*	.73*

ARIC = Atherosclerosis Risk in Communities; BMI = body mass index; ROC = receiver operating characteristic.

* Not significantly different.
