P980Physical activity and outcome in patients with atrial fibrillation
Bibliographic record
Abstract
Background: Increased physical activity (PA) is associated with an improved prognosis in healthy individuals and patients with cardiovascular diseases. However, the benefits of PA and the amount needed are much less clear among patients with atrial fibrillation (AF). Methods: The Basel Atrial Fibrillation Cohort study (BEAT-AF) is a prospective, multicenter cohort study that enrolled 1541 patients with documented AF. Patients reported whether they perform exercise on a regular basis. PA was quantified using the International Physical Activity Questionnaire (IPAQ). Three PA groups were defined: group 1: sedentary lifestyle; group 2: any moderate PA but no vigorous PA; group 3: any vigorous PA. The occurrence of all-cause death, cardiovascular death, major adverse cardiovascular events (MACE), major bleedings, heart failure hospitalization, stroke and myocardial infarction was assessed. To assess the relationships between PA and outcomes, Cox proportional hazards models were used to calculate hazard ratios (HR) and to adjust for clinically important confounders.

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.
