The presence of ventricular ectopic beats on a Holter monitor was initially an inclusion criterion for MADIT II. However, after 23 patients were recruited, the executive committee eliminated this criterion (1). Because those 23 patients represent less than 2% of the total enrolled sample in MADIT II, we believe their inclusion would only minimally influence interpretation of the ...Reference1.

Not 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.
