Effect sizes (adjusted ORs) of amounts of daily cigarette consumption and CYP2A6 genotypes on abdominal obesity in eight groups stratified by both daily cigarette consumption and CYP2A6 genotypes in 954 current male smokers with blood samples. The group that consumed 1–15 cigarettes/day and CYP2A6 normal metabolizer genotype was the reference group (OR=1). The adjusted variables were age, occupation, education, family income, alcohol consumption, exercise, coffee consumption, tea consumption, and BMI. The number of smokers in the eight groups were 243 (group 1), 73 (group 2), 146 (group 3), 83 (group 4), 198 (group 5), 64 (group 6), 108 (group 7), and 39 (group 8), respectively. N normal CYP2A6 metabolizer genotype, I intermediate CYP2A6 metabolizer genotype, S slow CYP2A6 metabolizer genotype, P poor CYP2A6 metabolizer genotype
