N = 84

Oxytocin plasma levels were taken twice at each visit — first sample before and second sample after a biographical interview. Data of patients is given twice, column 2 shows data of all MDD patients, columns 3 and 4 show the data according to the final outcome of the patients. Remission was defined based on the HAM-D score at the second visit (< 8). Differences in n’s are due to missing data. All oxytocin levels are given as [pg/ml]. Further details are summarized in the “Results” section
