Values are given as IRR (95% CI) P Value. CI indicates confidence interval; IRR, incidence rate ratio.
Pack‐y dose was analyzed as continuous variable and IRR corresponds to 10 cigarette pack‐y effect. Only current smokers and never smokers are involved in the analysis.
Adjusted for age, sex, education, physical activity, alcohol consumption in the past 12 mo, body mass index, hypertension, total cholesterol, and prevalent cardiovascular disease.
Model 1 plus waist circumference.
Model 2 plus high‐sensitivity C‐reactive protein.
