Figure 1. Receipt of diabetes preventive services by patterns of use.

HbA_1C = hemoblogin A_1C.

Note: Values are rates of receipt of services over a 2-year period. Microalbuminuria screening was assessed only in patients who did not have a prescription for an angiotension-converting enzyme inhibitor at baseline. Comparison of outcomes across use patterns are statistically significant (P <.001), except for the comparison of microalbuminuria screening (P = .05).
