Data are %. The upper limit of normal for HbA1c in the assay system is 6.1%, defined as the mean + 2 SD (5.27 + 0.85%) for the group of people with fasting plasma glucose <110 mg/dl and 2-h postchallenge glucose <140 mg/dl. Samples sizes for previously diagnosed hypertension (n = 618) and previously diagnosed dyslipidemia (n = 302) exclude subjects who have not been diagnosed with these conditions; dyslipidemia data also exclude subjects with triglyceride levels ≥400 mg/dl for whom the Friedewald equation to compute LDL cholesterol is not valid.
