Notes:

^a. Estimated after adjusting the model for 3 vs. 6 month study duration, participating with an informal caregiver, age, income bracket, and medical comorbidity. For ease of interpretabiity and comparability across dependent variables, the effect of week on nonadherence was estimated without the quadratic term (square root of week) in the model.

^b. All dependent variables are based upon IVR-reported data (coded as 0 = “problem did not occur” vs. 1 = “problem occurred”).

^c. Mean rate of problem across all available patient-weeks of participation.

^d. Adjusted odds ratio.

^e. Unadjusted p values are listed, but were evaluated against a Bonferroni – corrected criterion of p(crit) = 0.01.

^f. Adhering to antihyperglycemic medication less often than “always” during prior week.

^g. Not performing preprandial SMBG at least once during prior week.

^h. Not performing daily foot inspection during prior week.

ⁱ. Obtaining at least two SMBG results above 300 mg/dl during prior week.

^j. Obtaining at least one SMBG result below 90 mg/dl during prior week.
