The statistically significant indicators identified through univariate analysis served as independent variables, while patients’ levels of medication adherence were used as the dependent variable for constructing a binary logistic regression model. The magnitude and direction of regression coefficients (β) elucidate the relationship between the log odds of influencing factors and medication adherence. A positive β value implies that the log odds increase with the elevation of the independent variable, whereas a negative β value signifies a reduction in log odds. The odds ratio (OR) quantifies the extent to which log odds change per unit increase in the independent variable. An OR value of 1 denotes the absence of correlation between the independent and dependent variables. An OR value exceeding 1 indicates an augmented odds with the increase of the independent variable, while an OR value less than 1 indicates a decreased odds. Significance levels were denoted as and .
