Depression predicts perioperative outcomes following coronary artery bypass graft surgery
Bibliographic record
Abstract
OBJECTIVES: To assess preoperative depression in middle-aged men undergoing coronary artery bypass graft surgery (CABG) and to determine if depression is related to perioperative outcomes. DESIGN: One hundred and nine middle-aged male patients were randomly selected and assessed for depression one day before CABG using the Symptom Checklist-90 Revised (SCL-90R). Perioperative outcomes were: (1) postoperative length of hospital stay, (2) the presence of any early complications (at intensive care unit), and (3) the presence of any late complications (at cardiac surgery unit). RESULTS: Twenty-five (23%) patients had a high level of depression. Preoperative depression scores significantly predicted postoperative length of hospital stay (p < 0.001) and the incidence of late perioperative complications (p < 0.05) independently from biomedical and sociodemographic factors. Each increase in depression T score increased the odds of occurrence of late complications by 10% (p = 0.018, CI 95% 1.02-1.19). CONCLUSIONS: Depression is common in middle-aged men undergoing CABG and is an independent predictor of postoperative length of hospital stay and late perioperative complications.

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.
