What is the independent and dependent variable in this study?

Materials and Methods: A randomized controlled study involving patients with major depressive disorder (n = 80) were allocated to two groups, one received standard therapy (antidepressants and counseling) and the other received adjunct yoga therapy along with standard therapy. Ratings of depression and anxiety were done using Montgomery–Asberg Depression Rating Scale and Hospital Anxiety and Depression Scale at baseline, 10th and 30th day. Clinical Global Impression (CGI) Scale was applied at baseline and 30th day to view the severity of illness and clinical improvement.

Results: By the 30th day, individuals in the yoga group had significantly lower scores of depression, anxiety, and CGI scores, in comparison to the control group. The individuals in the yoga group had a significant fall in depression scores and significant clinical improvement, compared to the control group, from baseline to 30th day and 10th to 30th day. In addition, the individuals in the yoga group had a significant fall in anxiety scores from baseline to 10th day. Conclusion: Anxiety starts to improve with short-term yoga sessions, while long-term yoga therapy is likely to be beneficial in the treatment of depression.
