Screening for abdominal aortic aneurysms in Canada: 2020 review and position statement of the Canadian Society for Vascular Surgery
Bibliographic record
Abstract
Screening for abdominal aortic aneurysms in Canada: 2020 review and position statement of the Canadian Society for Vascular Surgery A n abdominal aortic aneurysm (AAA) occurs when the abdominal aorta is more than 3 cm in maximal diameter, about 1.5 times larger than normal. The development of AAAs is associated with tradi tional cardiovascular risk factors, such as smoking, age, male sex, hypercho lesterolemia and family history. As the aorta expands beyond its normal size, the risk of aortic rupture increases. Rupture is often fatal, with more than 80% of all patients with ruptured AAAs dying, many before hospital admission or even after emergent surgery. These aneurysms are often asymptomatic and therefore underdiagnosed, with symptoms occurring only once the aneurysm has ruptured or immedi ately before rupture.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
