However, our review focused on the management of acute exacerbations in the emergency department and in the hospital setting. Preventive measures and management of stable COPD were excluded from the review because they did not pertain to our specific research question. Drs. Niederman, Sethi, and Martinez favor the use of newer, broad-spectrum agents in the management of severe acute exacerbations of COPD. They base their recommendation on their view ...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.
