Abstract
Evidence-based medicine has changed clinical practice by incorporating data from randomised controlled trials (RCTs). While some biases in RCTs are well recognised, we discuss some less acknowledged. Selection bias may arise in the consent stage. Industry-funded studies more often report a positive outcome. Post-hoc changes of outcome measures and other mis-reporting lowers the reliability of outcome data. Finally, even the GRADE system retains subjectivity. CONCLUSION: Moving from "intuition" into "evidence-based" medicine involves grappling with several pitfalls. These pose challenges for authors, editors, reviewers, and readers. All require vigilance before drawing conclusions from presented data.

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, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
