You enrolled 6,500 men in 2005 and followed them for 10 years. Liver cancer is your outcome; none of the men had liver cancer at the start of the study. Of those men who drank alcohol daily (n=2,000) starting in 1990, 50 were diagnosed with liver cancer during the 10-year period. Of those who abstained from alcohol in 2005, 50 had liver cancer diagnosed during the 10-year period.
