Matched (cases and controls were matched for age and sex) univariate OR estimated by conditional logistic regression analysis.

Adjusted ORs (adjusted for alcohol drinking, corresponding tobacco user, level of education, occupation, and income group) obtained by matched conditional multiple logistic regression analysis using maximum likelihood approach.
