Results
A total of 220 patients met the eligibility criteria and were included
in the final analysis (Figure 1). Among them, 88 (40%) used mirtazapine
as an adjunctive antidepressant and 132 (60%) did not use. The majority
of patients (71.8%) were female. The mean age of the patients was 47.5
(SD:15.23) years and median duration of illness was 12 months (IQR: 56).
The mean interval between the two thyroid function tests (baseline and
after treatment) was 35.6 days (SD 22.54).
