Cox proportional hazard models adjusted for age, race, education, BMI, smoking intensity, physical activity, and alcohol consumption

The interaction between the combination of waist circumference and smoking and sex was borderline significant (p=0.06)

Age standardized mortality rates per 100,000 person years, standardized to the age distribution of the cohort in men and women
