In the MDD group, correlation analysis identified a significant positive correlation between leptin levels and “somatic anxiety” scores on the HAMD (r = 0.550, p = 0.024), but no significant correlation between leptin levels and scores for “psychic anxiety,” “core depressive,” “anorexia,” or total scores on the HAMD and HAMA (Table 2). The gene discussed is LEP; the disease is Anorexia.
