Abstract
Our study was designed as a screening test to offer anadditionaloptiontothebedsideportableDopplerAnkleBrachial Pressure Index (ABPI). ABPI is a difficult testto perform where an active ulcer is present over the areaof blood pressure cuff occlusion, when severe local painlimits the ability to perform the ABPI test or the vesselsare non-compressible (often in persons with diabetes)due to calcification with an ABPI level of greater than1.3. In our recent study, audible handheld Dopplerultrasound (AHDU) is a reliable simple bedside toolfor the screening of peripheral arterial disease with aspecificity of 97.5% and a negative predictive value of94.1%. The inter-rater reliability of the test performedbythephysicianandthenurseperformingAHDUintheclinic was very high with 87.5% agreement. Althoughthe sensitivity of the test is only 42.8%, it is a screeningtest that combined with physical findings to determinethe need for further vascular laboratory assessment.The study by Mustapha et al.

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 it
