A prospective cohort study was conducted over five years to explore a possible association between binge drinking and liver cirrhosis (a form of liver cancer) in a population-based cohort of adults between 20 to 60 years of age. Any prospective cohort study begins with a large disease-free group of participants, some with and others without the exposure of interest but all are essentially disease-free at baseline. This is followed by a monitoring period and at the end incidence (or risk) of disease is compared between exposed and the non-exposed groups. For this particular study follow up was five years and everybody was free of cirrhosis at the beginning. Among 5,009 adults who reported regular binge drinking, 1,554 developed liver cirrhosis. Among those who were not involved in binge drinking, a total of 10,523 adults, there were 81 cases of liver cancer diagnosed during the follow up period. Calculate Relative risk to see if there is any link between binge drinking and liver cirrhosis. Only the final answer is needed with two decimals after correct rounding. Please use brackets ( ) on your calculator to do the calculation in one go avoiding multiple steps that may give you slightly incorrect final answer. Only final answer is required and not the entire equation.What does a probability value or p value from a hypothesis test tells us? 0 It tells us we can retain null when it is <.os and reject null when it is .05 or higher. if hypothesis was correct there nothing going on in the population no correlation association between variables real difference groups etc p value tells us under those circumstances how likely are chance factors responsible for our ndings. true to simply focus words signicant not worry about devil details. false totally ndings>
