Area Under ROC Curve Using a Diabetes Risk Score, Family History of Diabetes, and BMI to Predict Development of Diabetes Within 10 Years

Predictors	Area Under ROC Curve
ARIC diabetes risk score	.70
Family history of diabetes
Parents	.57*
Siblings and parents	.58*
BMI
Continuous	.65†
3 categories	.67†
3 categories plus family history of diabetes (siblings and parents)	.69†

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

* Area under the curve significantly different from that of diabetes risk score.

† Not significantly different.
