Abstract
We investigated the role of oral vitamin K antagonists (VKAs) in graft patency, limb salvage, major and minor bleeding rates in patients undergoing infrainguinal bypass surgery. Five randomized-controlled trials (RCTs; n = 3746 patients) comparing VKA versus non-VKA treatment outcomes in patients undergoing infrainguinal bypass surgery were analyzed. The VKA treatment was associated with improved graft patency rates when a vein graft was used (risk ratio [RR]: 0.74; P = .0004), while there was no difference with prosthetic grafts (RR: 1.07; P = .39). The VKA treatment was also associated with improved limb salvage rates (RR: 0.33; P = .0008). Major and minor bleeding complications were higher in the VKA group. In conclusion, VKA treatment is associated with improved graft patency and limb salvage rates when a vein graft is used at the price of an increased risk of bleeding. Due to the inconsistent results, further well-designed RCTs are needed.

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
