Abstract
OBJECTIVE: To assess the relative antidepressant efficacy of escitalopram and comparator antidepressants. RESEARCH DESIGN AND METHODS: A meta-analysis was performed using studies in major depressive disorder (MDD) comparing escitalopram with active controls, including selective serotonin reuptake inhibitors [SSRIs] (citalopram, fluoxetine, paroxetine, sertraline) and serotonin/noradrenaline reuptake inhibitors [SNRIs] (venlafaxine, duloxetine). Adult patients had to meet DSM-IV criteria for MDD. MAIN OUTCOME MEASURES: The primary outcome measure was the treatment difference in Montgomery-Asberg Depression Rating Scale (MADRS) total score at week 8. Secondary outcome measures were response and remission (MADRS total score < or = 12) rates. RESULTS: Individual patient data (N = 4549) from 16 randomized controlled trials were included in the analyses (escitalopram n = 2272, SSRIs n = 1750, SNRIs n = 527). Escitalopram was significantly more effective than comparators in overall treatment effect, with an estimated mean treatment difference of 1.1 points on the MADRS (p < 0.0001), and in responder (63.7 vs. 58.3%, p < 0.0001) and remitter (53.1 vs. 49.4%, p < 0.0059) analyses. Escitalopram was significantly superior to SSRIs, with an estimated difference in response of 62.1 vs. 58.4% and remission of 51.6 vs. 49.0%. In comparison to SNRIs, the estimated difference in response was 68.3 vs. 59.0% (p = 0.0007) and for remission the difference was 57.8 vs. 50.5% (p = 0.0088). These results were similar for severely depressed patients (baseline MADRS > or = 30). Sensitivity analyses were performed with data from articles reporting Hamilton Rating Scale for Depression (HAMD) scores. The 8-week withdrawal rate due to adverse events was 5.4% for escitalopram and 7.9% for the comparators (p < 0.01). This difference was accounted for by statistically significant higher attrition rates in the SNRI comparisons. This work may be limited by the clinical methodology underlying meta-analytic studies, in particular, the exclusion of trials that fail to meet predetermined criteria for inclusion. CONCLUSIONS: In this meta-analysis, superior efficacy of escitalopram compared to SSRIs and SNRIs was confirmed, although the superiority over SSRIs was largely explained by differences between escitalopram and citalopram.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
