Project #43079 - Epidemiology Assignment 2

Please see attachment for instructions and Table In the second relative risk problem of Lesson 6 Assignment 2 the denominator = 0 for part a. You can not calculate with a zero in the denominator. This means that the risk is so high that it can not be calculated Assignment: Answer the study guide questions #1-12 on page 119 of your textbook. Complete the following risk calculations for cohort studies: A) A cohort study was conducted to study the association of coffee drinking and anxiety in a population-based sample of adults. Among 10,000 coffee drinkers, 500 cases of anxiety were observed. Among 20,000 adults who do not drink coffee, 200 cases of anxiety were observed. Construct a 2x2 contingency table for the data. What is the relative risk of anxiety associated with coffee use? B) Of 2,872 people who had received radiation treatment in childhood because of enlarged thymus, cancer of the thyroid developed in 24 and benign thyroid tumor developed in 52. A comparison group consisted of 5,055 children who had received no such treatment (brothers and sisters of those who had received radiation treatment). During the follow-up period, none of the comparison group developed thyroid cancer, but benign thyroid tumors developed in 6. Fill in the tables below. Calculate the relative risk for benign thyroid tumors. Calculate the relative risk for thyroid cancer. Explain the results. Please see attachment for the table
