Adjusted Risk Models Predicting Low Adherence to Medicines
| Model 1 (Includes Barriers Only) | Model 2 (Includes Beliefs Only) | Model 3 (Includes Both Barriers and Beliefs) | |
|---|---|---|---|
| Any barrier | 0.53 (0.33–0.87) | NA | 0.68 (0.39–1.19) |
| Higher negative beliefs | NA | 0.47 (0.27–0.80) | 0.51 (0.29–0.88) |
Data are relative risk (95% confidence interval). Models 1 and 2 look at the 2 independent variables alone (ignoring the other). Model 3 adjusts the risk of barriers given beliefs and vice versa. All 3 models are adjusted for race (white), education, income, number of medicines, and disease burden.
