Note: Boldface indicates statistical significance (p<0.05).

Proportions and ORs estimated by GEE taking into account intra-cluster correlations. When age, gender, education, depression, tradition tobacco use, and time to first cigarette were included as covariates: ^c,fN=231, ^d,g N=202.

Denominator changes due to missing values.

Not all responders provided saliva. Those not providing saliva were categorized as smokers. ANBL, All Nations Breath of Life; CBP, Current Best Practices; GEE, Generalized Estimation Equations
