Abstract
Prostate-specific antigen screening I read Dr Robert Burn’s letter on prostate-specific anti-gen screening1 with personal interest, having recently been declared “cured ” [of prostate cancer] 6 years after brachytherapy (radioactive iodine) treatment. Given that my father had incidental prostate cancer later in his life, and considering myself to be at some increased risk, I enrolled in the multicentre SELECT (Selenium and Vitamin E Cancer Prevention Trial) study some 10 years ago. The purpose of the study was to test, in a double-blinded trial, the hypothesis that selenium or vitamin E might decrease the incidence of prostate cancer. (The study was abandoned when it was found that the incidence of type 2 diabetes increased with one of the drugs and the incidence of prostate cancer slightly increased with the other. Incidentally, on inquiry

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
