Abstract

fetched live from OpenAlex

For new interventions, the results of sequential randomized or non-randomized trials and meta-analysis can differ significantly. Evaluation of the evidence for the effect of a new treatment is a complex interplay of several factors, including the methodological design, the risk of a coincidental finding and applicability in practice. For proper appraisal of the design of trials, the use of aggregate scores should be avoided and individual study limitations should be mentioned. With the use of additional analyses we can now test whether meta-analyses contain sufficient data to find potentially relevant differences. The new 'Grading of recommendations assessment, development and evaluation' (GRADE) system is a consensus guideline that combines multiple factors into an easily interpreted judgment of the strength of evidence. Concise presentation of important quality factors for each outcome significantly increases clarity. A more realistic assessment of the reliability of the evidence decreases the risk of major fluctuations in treatment policy

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.
