Research and scholarly methods: Appraising the available literature to inform a research project
Bibliographic record
Abstract
Abstract A literature review with an evaluation of existing evidence is often the first step in designing a research project. This article provides a systematic framework and guide for clinicians, researchers, and clinician‐scientists to appraise the available literature to inform a clinical research project. The three‐step approach outlined in this article starts with defining your research question using the Population Intervention Comparator Outcome‐Design framework, followed by evaluation of the existing evidence and identification of gaps that could be addressed by a research project, and ends with guidance to refine the research question and start preparing a protocol.

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 machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedLabeled directly by 2 models reading the full record.
