Abstract

fetched live from OpenAlex

Physical activity is associated with a lower risk of disease recurrence among colon cancer survivors. Excess visceral adipose tissue is associated with a higher risk of disease recurrence among colon cancer survivors. The pathways through which physical activity may alter disease outcomes are unknown, but may be mediated by changes in visceral adipose tissue. Thirty-nine stage I–III colon cancer survivors were randomised to one of three groups: usual-care control, 150 min wk −1 of aerobic exercise (low dose) and 300 min wk −1 of aerobic exercise (high dose) for 6 months. The prespecified key body composition outcome was visceral adipose tissue quantified using dual energy X-ray absorptiometry. Exercise reduced visceral adipose tissue in dose–response fashion ( P trend =0.008). Compared with the control group, the low- and high-dose exercise groups lost 9.5 cm 2 (95% CI: –22.4, 3.5) and 13.6 cm 2 (95% CI: –27.0, –0.1) in visceral adipose tissue, respectively. Each 60 min wk −1 increase in exercise predicted a 2.7 cm 2 (95% CI: –5.4, –0.1) reduction in visceral adipose tissue. Aerobic exercise reduces visceral adipose tissue in dose–response fashion among patients with stage I–III colon cancer. Visceral adipose tissue may be a mechanism through which exercise reduces the risk of disease recurrence among colon cancer survivors.

Not 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.
