Abstract
To the Editor: In my recent commentary,1 I had noted some confusion over the nomenclature for measures of the potential impact of an intervention on risk in a community. I underestimated the complete range of terminology, however. Soon after my commentary appeared, Noel Weiss pointed out to me that a measure Tom Koepsell and he had called attributable risk to the population (PAR) in their 2003 textbook2 is identical to attributable community risk (ACR), as used in MacMahon et al3 and my commentary.1 Koepsell and Weiss refer to the measure commonly called PAR as attributable risk to the population percent (PAR%) and clearly indicate the distinction between the questions addressed by the 2 measures.2 The percent in “PAR%” refers to the percentage of cases attributable to the exposure, not the percentage of the population who develop the disease due to the exposure. I also underestimated the complete range of confusion. Although Professor Weiss taught me PAR and PAR% in class in 1977, I did not appreciate the importance of the distinction for a quarter century.

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.
