Abstract

fetched live from OpenAlex

Cardiac catheterization is a key step in the diagnosisand management of coronary artery disease(CAD). Recent advances in percutaneous coronary interventions (PCI) and coronary artery bypass grafting (CABG) have enhanced options for the management of patients and have led to considerable expansion of the availability of cardiac catheterization across Canada and elsewhere. Whether our catheterization rates are appro-priate has been debated for almost 2 decades. In 1988/89, the average rate in Canada was 236 per 100 000 (range 194 in the Atlantic provinces to 280 in Alberta).1 A recent re-port has shown much higher rates across the country (e.g., 500 per 100 000 in Ontario in 2001/02) that are compara-ble to many in European countries but are still consider-ably lower than rates in the United States.2,3 The question remains: Are Canadian catheterization rates optimal, too low or too high? In this issue (page 35), Graham and colleagues4 attempt to determine the optimal population rate for cardiac catheterization. Using data collected between 1995 and

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.
