Abstract
The purpose of this study was to compare the free TRAM to the unipedicled TRAM flap in postmastectomy reconstruction, using a cost-utility analysis. A decision analytic model was used for this study. Medical costs associated with the two techniques were estimated from the Ontario Ministry of Health Schedule of Benefits (1998). Hospital costs were obtained from St. Joseph's Healthcare, a university hospital in Hamilton, Ontario. Utilities were obtained from 33 "experts" across Canada and then converted into quality-adjusted life-years (QALYs). The probabilities of various health states associated with unipedicled and free TRAM flaps were obtained by reviewing several key articles. The free TRAM flap was more costly than the unipedicled TRAM flap, but it provided more QALYs. The baseline incremental cost-utility ratio (ICUR) was $5,113.73/QALY, favoring adoption of the free TRAM flap. This study showed that the free TRAM flap is a cost-effective procedure for postmastectomy reconstruction in the Canadian healthcare system.

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
