  • Data are means ± SD and means (range) unless otherwise indicated. Follow-up years are mean values. —, the study did not record this information.

  • *

    * Studies that contributed to all three age-groups provided baseline data on diagnosis of diabetes and potential confounders (systolic blood pressure, total cholesterol, smoking, and BMI).

  • Weighting by person-years of follow-up (total person-years of follow-up was 1,194,320 for fasting glucose and 185,324 for nonfasting glucose).
