  1. Data are expressed as means (standard deviations) or as frequencies (%).
  2. p-values (adjusted for age) for differences between means were calculated using a covariance analysis (ANCOVA, apart from the non-adjusted p-value for age), or using multivariable logistic regression analyses with variables shown as proportions.
  3. a2 hPG was assessed in participants not known to have diabetes.
  4. Abbreviations: BMI: body mass index; DBP: diastolic blood pressure; FPG: fasting plasma glucose; HDL-C: high density lipoprotein cholesterol; LDL-C: low density lipoprotein cholesterol; SBP: systolic blood pressure; TC: total cholesterol; TG: triglyceride; 2 hPG: 2 h post-load plasma glucose.
