Toe Pressure As A Standalone Vascular Assessment Of The Foot
Bibliographic record
Abstract
This study aims to verify whether toe pressure (TP) or toe-brachial index (TBI) has better thresholds of sensitivity/specificity for PAD detection. A single-centre retrospective analysis was conducted of prospective data collected on 108 ambulatory patients recruited at the Complex Wound Care Clinic in Canada. Patients were included with any kind of lower limb wound without regard to any diagnosis of chronic kidney disease, diabetes, PAD or CLTI. TP with photoplethysmography (PPG) and laser Doppler flowmetry, dorsalis pedis and posterior tibialis arteries waveforms have been assessed. Of 108 patients, (40%) presented with monophasic dorsalis pedis arteries (DPA) indicating insufficient vascularization on the left foot and 34 (31%) on the right foot and 55% of the patients had diabetes. The study showed toe pressure seems to be a standalone vascular test of the forefoot, while performing the calculation of TBI appears to be of no added values for detecting PAD, based on this study.

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.
