Ten-year risk of diagnosed diabetes (self-reported diagnosis or medication use) by baseline fasting glucose and/or A1C categories in the ARIC study, adults without a history of diagnosed diabetes (n = 12,485). A: 10-year risk of diagnosed diabetes by fasting glucose category at baseline. B: 10-year risk of diagnosed diabetes by A1C category at baseline. C: 10-year risk of diagnosed diabetes by A1C and fasting glucose categories at baseline. I bars are 95% CIs.

Area under the ROC curve for A1C (%) for the detection of glucose-based definitions of diabetes, the ARIC study (n = 12,485), adults without a history of diagnosed diabetes. ——, ROC curve for definition 1 (fasting glucose ≥126 mg/dl at baseline), AUC 0.892; – – –, ROC curve for definition 2 (fasting glucose ≥126 mg/dl on two separate occasions, 3 years apart), AUC 0.936.
