Symptoms and distress in patients awaiting coronary artery bypass surgery.
Bibliographic record
Abstract
In this examination of symptom distress in patients awaiting coronary artery bypass graft (CABG) surgery, a convenience sample of 42 patients on a waiting list for first-time CABG-only surgery were contacted via mail as part of a larger study into the experience of waiting for CABG surgery. They were asked to respond to questions about the frequency and distress of their coronary artery disease symptoms. A modified version of the Symptom Frequency and Symptom Distress Scale (SFSDS) was used. The mean symptom distress score was 77.7 out of a possible 386. Strong correlations were established between each individual item on the scale and the total score. The most frequent and distressing symptoms were fatigue, shortness of breath with activity, and chest pain. The most frequent' symptoms were also the most distressing. The findings underscore the significance of symptom experience in patients on a waiting list for CABG surgery and also point to the need for further testing of this version of the SFSDS.

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.
