Abstract
The study aimed to summarize clinical data for escitalopram in the treatment of major depressive disorder in primary care. Medline, Embase and Cochrane databases were searched for randomized controlled trials of escitalopram (10-20 mg/day for 8 weeks) versus other antidepressants in therapeutic doses or placebo. Patients were required to have had moderate/severe depression, with Montgomery-Asberg Depression Rating Scale (MADRS) scores recorded at baseline and 8 weeks. Outcomes examined were remission rates (MADRS</=12) and response rates (>/=50% decrease from baseline in MADRS at week 8). Data were combined using a random effects meta-analytic model. Of the 15 studies identified, 11 were rejected (five not primary care, four duplicate reports, one lacked 8-week MADRS scores, one not depression) and four were accepted (n=1472 patients). The four studies had nine arms, four for escitalopram (n=654), two for citalopram (n=333), one for venlafaxine-XR (n=142) and two for placebo (n=343). Remission rates for escitalopram were superior to placebo (48.7% versus 37.6%, P=0.003) and citalopram (52.8% versus 43.5%, P=0.003) but similar to venlafaxine-XR (P=0.97). Response rates were superior to placebo (48.7% versus 43.1%, P<0.001) and citalopram (62.5% versus 49.5%, P=0.001) but not venlafaxine-XR (P=0.52). Adverse events were comparable among active drugs (P<0.05). Remission rates for escitalopram were superior to placebo (48.7% versus 37.6%, P=0.003) and citalopram (52.8% versus 43.5%, P=0.003) but similar to venlafaxine-XR (P=0.97). Response rates were superior to placebo (48.7% versus 43.1%, P<0.001) and citalopram (62.5% versus 49.5%, P=0.001) but not venlafaxine-XR (P=0.52). Adverse events were comparable among active drugs (P>0.05). Remission and response rates of escitalopram in primary care are clinically superior to placebo and citalopram, but similar to venlafaxine-XR. Further head-to-head trials are warranted to verify these findings. A pharmacoeconomic analysis is also required to determine whether these clinical advantages for the patients translate into economic advantages for the health care system.

Full frame distilled prediction
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
