We acknowledge that a discussion of these matters is important, because our findings could influence the care of many patients.First, they indicate that Cohen and colleagues (1) did not confirm all fatal PEs with autopsy. They propose that this would overestimate the risk for such events. We included these events because, in accordance with our prespecified criteria, they were independently adjudicated as fatal PEs.Second, they questioned our decision to extract data from only the first 21 ...References1.

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.
