A cohort study was conducted to investigate the association between alcohol consumption and bladder cancer. The study population includes 200 men in Community X who were aged 55-69 years at baseline. All subjects completed a self-administered questionnaire which includes common risk factors for cancer including alcohol consumption patterns. Subjects were followed up for 6 years through record linkage to cancer registries. Table 1 shows the data gathered at the end of the follow-up period.
