Abstract
The prostate specific antigen (PSA) test should not be used to screen for prostate cancer, the Canadian Task Force on Preventive Health Care has said. “Available evidence does not conclusively show that PSA screening will reduce prostate cancer mortality, but it clearly shows an increased risk of harm,” the task force said. The task force is an independent panel established by the Public Health Agency of Canada to develop clinical practice guidelines for preventive services provided in primary care. The panel’s recommendations, which were based on a systematic review, were published online on 27 October by CMAJ , the journal of the Canadian Medical Association.1 “Unfortunately the PSA test is simply not an effective screening tool,” said Neil Bell, chair of the guideline working group …

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.
