Table 6

Patients-reported adherence to their medication regimen before and after intervention: Medtable versus usual care.

	Time	Medtable	Usual care	Unadjusted intervention effect (ITT)		Adjusted intervention effect (ITT)
		Mean (SD)	Mean (SD)	OR (95% CI)	value	OR (95% CI)	value
Regimen adherence score	Baseline, preintervention	0.80 (0.26)	0.84 (0.23)	0.83 (0.72, 0.96)	0.0115	0.78 (0.68, 0.91)	0.001
	Month 3	0.82 (0.19)	0.81 (0.20)	1.09 (0.95, 1.25)	0.2028	1.05 (0.92, 1.21)	0.4636
	Month 6	0.80 (0.20)	0.75 (0.21)	1.17 (1.03, 1.32)	0.0156	1.13 (0.999, 1.29)	0.0526

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.
