Abstract
BACKGROUND: Few prospective studies have examined quantitative cigarette consumption and smoking cessation on sudden cardiac death (SCD) risk with long-term follow-up. METHODS AND RESULTS: We prospectively examined the association between cigarette smoking and smoking cessation on the risk of SCD among 101 018 women participating in the Nurses' Health Study without known coronary heart disease, stroke, and cancer at baseline 1980. During 30 years of follow-up, we identified 351 SCD events. Compared with never smokers, current smokers had a 2.44-fold (95% CI, 1.80-3.31) increased risk of SCD after controlling for coronary risk factors. In multivariable analyses, quantity of cigarettes smoked daily (P value for trend, <0.0001) and smoking duration (P value for trend, <0.0001) were linearly associated with SCD risk among current smokers. Small-to-moderate amounts of cigarette consumption (1-14 per day) were associated with a significant 1.84-fold (95% CI, 1.16-2.92) increase in SCD risk and every 5 years of continued smoking was associated with an 8% increase in SCD risk (hazard ratio, 1.08; 95% CI, 1.05-1.12; P<0.0001). The SCD risk linearly decreased over time after quitting and was equivalent to that of a never smoker after 20 years of cessation (P value for trend, <0.0001). CONCLUSIONS: In this large prospective cohort of women without coronary heart disease at baseline, a strong dose-response relationship between cigarette smoking and SCD risk was observed, and smoking cessation significantly reduced and eventually eliminated excess SCD risk. This suggests efforts to prevent SCD among women should include aggressive strategies for smoking cessation.

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 it
