Reply: The forced correlation between ISCHEMIA and the inaccurate CABG recommendations of the 2021 American College of Cardiology/American Heart Association/Society for cardiovascular Angiography coronary revascularization guidelines
Bibliographic record
Abstract
We appreciate the Letter to the Editor by Maron and colleagues regarding our manuscript addressing reasons for not endorsing the 2021 American College of Cardiology/American Heart Association/Society for Cardiovascular Angiography and Interventions Coronary Revascularization Guidelines.1-3 First, we congratulate the authors of the ISCHEMIA trial (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches) report on a well-conducted study providing reassuring data regarding the safety of initial conservative management of patients with low atherosclerotic burden and normal ventricular function.

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.
