ITT: intention-to-treat analysis. Covariates used for adjustment were health literacy (REALM), Letter Comparison test, Pattern Comparison test, diabetes mellitus knowledge, diabetes self-care: diet, diabetes self-care: exercise, diabetes self-care: glucose testing, years with diabetes mellitus, Comorbidity Index, general health, age, gender, race, patient education, research site, and Medication Regimen Complexity Index.
