Notes: Model 1: Adjusted for medication belief. Model 2: Adjusted for the perception of illness (overall score) and age, sex, NIHSS, education, occupation, duration of disease, and payment methods. Model 3: Adjusted for model 1 and each of the domains of the perception of illness, and age, sex, NIHSS, education, occupation, duration of disease, and payment methods.
