  • Data are ORs (SE) or predictive margin (SE). Results control for age, sex, race/ethnicity, education, BMI, insurance, income, and duration of diabetes. Treatment variables include use of diabetes pills only, insulin only, and insulin and diabetes pills; the treatment variable omitted is diet only.

  • * ORs are significantly different from 1999–2000 at P < 0.05.
