  • Adjusted for age, minority status, hypertension, cholesterol, cardiovascular disease, overweight, primary care specialty, number of primary care visits, and number of specialty visits.

  • *Significance at P < 0.05;

  • †high-risk factors generated from the ADA screening criteria, as defined previously (6);

  • ‡primary care specialty determined for each patient by specialty in which the majority, or all, of their primary care visits occurred;

  • §number of primary care, specialty, and total visits is mean number of visits per patient over the time period 1 January 2005–31 December 2007.
