A cohort study was conducted over five years to study the association between binge drinking and liver cirrhosis, a form of liver cancer in a population-based sample of adults between 20 to 60 years of age. Among 3179 adults who reported regular binge drinking, 800 developed liver cirrhosis during five-year follow up. Among those who were not involved in binge drinking, a total of 5295 adults there were 442 new cases of liver cancer diagnosed during this follow up. Calculate Attributable risk to work out how much risk of liver cirrhosis can be attributable to, or due to, binge drinking. Express your answer as PROPORTION, and not as percentage, which means DO NOT MULTIPLY YOUR EQUATION WITH 100. Use two decimal places.
