BMQ-Specific
Necessity	437	18.63 (3.54)	18.70 (3.56)	0.884	0.97 (0.89–1.06)	0.496
Concern	430	11.68 (4.43)	12.27 (4.12)	0.349	0.95 (0.88–1.03)	0.201

Notes: Mean values ± SD and independent two-sample t-tests. Multivariable analyses presented with OR and 95% CI, comparing primary non-adherers with adherers. *Adjusted for dependence on help/support from next of kin, difficulties with memory, and each BMQ subscale.

Abbreviations: BMQ, Beliefs about Medicines Questionnaire; SD, standard deviation; OR, odds ratio; 95% CI, 95% confidence interval.
