^aAdjustment was done for age, gender, literacy level, illness duration, number of medical illnesses, comorbidities, number of medications, beliefs, and perceived medication information adequacy. Only significant variables found in the regression analysis in addition to beliefs are presented in this table.

Note: in the used linear regression model Intercept = 5.387; R ² = 0.78;  F = 89;  P < 0.001; df = 16; r: Pearson's bivariate correlation coefficient; β: multiple linear regression coefficient; CI: confidence interval; BMQ: beliefs about medicines questionnaire; *P < 0.05; **P < 0.01; ***P < 0.001.
