Abstract

fetched live from OpenAlex

OBJECTIVE: To determine the feasibility and effectiveness of androgen treatment of depressive symptoms in older men. METHOD: We searched MEDLINE, PsycINFO, Eric, HealthStar, and the Cochrane Database of Systematic Reviews for potentially relevant articles. The bibliographies of relevant articles were searched for additional references and experts were consulted. Seventeen reports (8 open and 12 randomized trials; 3 articles reported studies of 2 designs) met the following inclusion criteria: original investigation; published in English or French, use of acknowledged criteria or scale for depression, and open or randomized trial of androgen treatment. Four criteria assessed study validity: randomization, double blinding, comparability of treatment and control groups at baseline, and description of dropouts. We abstracted, tabulated, and compared information from each article. RESULTS: Most studies had methodological limitations. With regard to feasibility, there were few reported withdrawals due to adverse events. With regard to effectiveness, 6 of 8 open trials had positive results, and 5 of 12 randomized trials had positive results, although 1 was equivocal. However, testosterone was combined with antidepressant medication in 3 of these positive randomized trials. Only 2 open trials enrolled subjects whose mean age was 60 years or over. One had positive results, and the other had negative results. CONCLUSION: Androgen therapy may be feasible in the short term, but there is little evidence that it is an effective treatment for depressive symptoms in older men.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
