Abstract

fetched live from OpenAlex

This review provides an overview of 59 randomized placebo-controlled trials that examined the analgesic effect of antidepressants. To summarize, there is significant evidence that the tricyclic group of antidepressants is analgesic and that trazodone is not; the data regarding selective serotonin reuptake inhibitors are conflicting. To date, there are no randomized controlled trials examining the potential analgesic action of nefazodone or venlafaxine, but on the basis of initial clinical reports and its structural similarity to other analgesics, venlafaxine shows promise as an analgesic.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
