51 Coronary Artery Bypass Graft Harvest Site and Post-Op Recovery in Women
Bibliographic record
Abstract
Purpose: To examine the relationships between coronary artery bypass graft (CABG) harvest site (saphenous, internal mammary arteries (IMA) or both) and surgery-related pain, functional status and health services utilization in women at 6 weeks, 12 weeks, and 12 months post-operatively. Methods: This was a sub-study of the Women's Recovery from Sternotomy Trial (WREST; registration number ISRCTN 47669580) which tested the use of a novel undergarment for women following first-time sternotomy. Women (222) who underwent CABG surgery or CABG plus valve surgery and completed the 12 month follow-up survey were included in these analyses. Harvest site data were collected through a health record audit and categorized into (1) left internal mammary artery (LIMA) only, (2) bilateral internal mammary arteries (BIMA), (3) saphenous vein only, or (4) saphenous vein and LIMA or BIMA. Blinded centrally located research assistants collected data on primary outcomes related to surgery-related pain (numeric rating scale), functional status (Health Assessment Questionnaire), and health services utilization (including pain medication use; by standardized interview) at 6 weeks, 12 weeks and 12 months following CABG surgery.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
