Abstract

fetched live from OpenAlex

A small number of general, broad interest journals contain the most clinically relevant information for doctors, according to a major review. The review was conducted by a group at McMaster University, Hamilton, Ontario. The Health Information Research Unit of the university's Department of Clinical Epidemiology and Biostatistics publishes several secondary “evidence-based” journals. In 2,000 the unit prepared ACP Journal Club ( ACP J Club ) to support internal medicine and Evidence-Based Medicine ( EBM ) to support general and family practice. The authors of the review found that four journals ( New England Journal of Medicine , JAMA , Lancet and the Cochrane Database Systematic Reviews ) provided 56.5% of the content for the internal medicine review journal ACP Journal Club …

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.
