Abbreviations: BDI, Beck Depression Inventory; HC, healthy control; MADRS, Montgomery–Åsberg Depression Rating Scale; MDD, major depressive disorder.

With the exception of BDI scores, the remitted MDD patients and HC group did not significantly differ on the demographic variables (contingency coefficient <0.008, p(unc)>0.94; t<0.79, p(unc)>0.43). In addition, with the exception of BDI scores, the remitted melancholic MDD patients and HC group did not significantly differ on the demographic variables (contingency coefficient <0.08, p(unc)>0.52; t<1.30, p(unc)>0.20). With the exception of years of education, the remitted melancholic and nonmelancholic MDD patients did not significantly differ on the demographic variables (contingency coefficient <0.17, p(unc)>0.18; t<0.89, p(unc)>0.38).

^aSignificantly different between the remitted melancholic and nonmelancholic MDD groups (t(61)=2.61, p(unc)=0.01).

^bSignificantly different between the remitted MDD and HC groups (t(99)=3.71, p(unc)<0.0001), and between the remitted melancholic MDD and HC groups (t(69)=4.06, p(unc)<0.0001).
