Demographic Variables HC

(N=63)		 Melancholic rMDD
(N=33)		 Non-Melancholic rMDD
(N=30)
Mean SD Mean SD Mean SD Mean SD

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). Also 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 non-melancholic 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). BDI, Beck Depression Inventory; HC, healthy control; MADRS, Montgomery-Åsberg Depression Rating Scale; MDD, major depressive disorder; SD, standard deviations.
