1Unadjusted odds ratio (95% confidence interval); 2adjusted odds ratios (95% confidence interval) in the multivariable model that included the variables listed in the left column in addition to education and secondhand smoke; 3adjusted odds ratios (95% confidence interval) in the multivariable model that included the variables in the left column (except residence and tumor grade), education, and secondhand smoke; 4Schistosoma haematobium; whenever smoking was assessed, pack-year for ever-smokers was included in the model.
