The figure shows the median Patient Health Questionnaire-9 (PHQ-9) scores of patients receiving specific auricular acupuncture (SA) and nonspecific auricular acupuncture (NSA) at baseline, 4 weeks, 6 weeks, and 3 months. A score of 10 to 14 indicates moderate depression; 15 to 19, moderately severe depression; and 20 to 25, severe depression. The lines inside the boxes reflect the medians, with the upper and lower ends of the boxes reflecting the IQRs. The error bars reflect the minimum and maximum values. The line plot reflects means.
