Abstract
In Brief This study evaluated the recipient and donor site complications associated with breast reconstruction using a deep inferior epigastric artery perforator flap (DIEAP) flap compared with a free TRAM flap. The charts of 108 patients who underwent breast reconstruction using these techniques were reviewed. There were 130 flaps. Patients with free TRAM flaps had a significantly longer hospital stay (P = 0.003). There were significantly more cases of fat necrosis in the unilateral DIEAP flaps (P = 0.001). In patients who were overweight or obese (body mass index >25 kg/m2), there were significantly more breast complications (P = 0.006). There were more cases of abdominal flap necrosis at the donor site in smokers (P = 0.018) and the diabetic patients (P = 0.013). This study suggests that postoperative complications are related to patient comorbidities, and personal factors and should be considered when selecting the most appropriate reconstructive option. A comparison study of 130 unilateral and bilateral free TRAM flaps and DIEAP flaps for breast reconstruction showed longer hospital stays for TRAM flaps, greater fat necrosis in unilateral DIEAP flaps, and greater abdominal flap necrosis in smokers and diabetics.

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
