A Comparison of Physical Activity of Posttreatment Breast Cancer Survivors and Noncancer Controls
Bibliographic record
Abstract
The authors obtained data from 335 breast cancer survivors and 6,880 noncancer controls. They proposed (1) to determine whether, after treatment, the survivors were meeting the Center for Disease Control and Prevention/American College of Sports Medicine recommendations for physical activity and were similar to the controls in physical activity and (2) to compare the modes of activity of the 2 groups in frequency, min/session, and sessions/wk. Adjusted logistic regression analyses revealed that the breast cancer survivors engaged in as much moderate, vigorous, and combined physical activity as the noncancer controls did. However, chi-square analyses showed that survivors engaged in more yard work than the controls did, whereas independent-sample t tests showed that the frequency and the total min/wk of stretching were significantly higher in breast cancer survivors compared with noncancer controls. Findings from the study suggest that breast cancer survivors engage in as much physical activity as controls do, but that the groups differ in specific activities.

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.
