Demographic characteristics, laboratory biochemical indicators, and scores from questionnaire surveys were systematically gathered from a total of 152 participants. Based on the MMAS-8 scores (≥6 representing good adherence and <6 representing poor adherence), patients were categorized into distinct groups. Differences of diverse variables between these groups were examined using appropriate statistical methods (the t-test for normally distributed continuous variables and the Chi-square test for categorical variables). Significance levels were marked as and .
