Abstract

fetched live from OpenAlex

Every 2 months, a brand new issue of Evidence-Based Medicine containing 20 abstracts is published. The compact appearance belies the mounds of sifting required to arrive at the finished journal. Readers should know, though, that the process for winnowing these select articles from the published literature is systematic and thorough. This article describes the 2-stage process of validity checks followed by a rating by clinicians for relevance that is used to selected articles. Journal staff hand search 140 journals and examine each original study or review. This hand searching amounts to 60 000 articles that are annually assessed. The 140 journals include the highly rated general medical journals ( Lancet , N Eng J Med , JAMA , BMJ , CMAJ , Ann Int Med , and Cochrane reviews), plus various speciality journals that are selected on the basis of article yield—we …

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction

Teacher imitation

Not 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.
