Outcomes
Primary outcome [1] 5840 0
Montgomery-Asberg's Depression Rating Scale (MADRS) (remission score < 12)
The genotypic frequencies of serotonin transporter gene were compared between remitters and non-remitters to escitalopram medication. Additionally, the mean change on the MADRS scale was compared between serotonin transporter genotypes at week 12 of escitalopram medication.
Timepoint [1] 5840 0
The primary outcome was measured at the following time points: week 0, 2, 4, 6, 8, 10 and 12
Secondary outcome [1] 241850 0
Hamilton Rating Scale for Depression (HRSD) (remission score < 8)
The genotypic frequencies of serotonin transporter gene were compared between remitters and non-remitters to escitalopram medication. Additionally, the mean change on the HRDS scale was compared between serotonin transporter genotypes at week 12 of escitalopram medication.
Timepoint [1] 241850 0
The secondary outcome was measured at the following time points: week 0, 2, 4, 6, 8, 10 and 12
