Abstract

fetched live from OpenAlex

Patients present with specific problems against a background of their particular situation. The applicability of a treatment to a specific case may be difficult to assess in the light of the information available on that treatment. Evidence-based medicine is a discipline developed to achieve the best informed treatment decisions in clinical situations. In this paper, we illustrate a logical approach to reaching a decision regarding which of two migraine treatments should be used in a clearly defined patient. The information evaluated is a comparative trial between sumatriptan (100 mg), rizatriptan (5 and 10 mg) and placebo. The use of the analytical tools of evidence-based medicine is demonstrated in this exercise. The example was chosen because this is an area of great current interest in the field of neurology.

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.
