  1. Data are from the combined 1999–2000 and 2001–2002 National Health and Nutrition Examination Surveys. Non-standard abbreviations are NFG, normal fasting glucose, IFG, impaired fasting glucose, DFG, provisional diagnosis of diabetes, tHcy, total plasma homocysteine, SBP, systolic blood pressure, TC, total lipoprotein cholesterol, and CCr, estimated creatinine clearance. Values are mean ± standard error, except for tHcy, which was log transformed because of its highly skewed distribution and is presented as median with 95% confidence interval (antilog values).
