QUESTION 3 A prospective cohort study was conducted to investigate a possible relationship between Diet and Attention-Deficit Hyperactivity Disorder (ADHD) in children. After assessing dietary habits of a sample of young pre-school children (who were all free of ADHD at baseline) they were categorised as either 'Healthy eaters' or 'Unhealthy eaters' and were followed up for the next three years. At the end of the follow-up period, there were a total of 6642 children in the Unhealthy eaters group (exposed) and 504 had developed ADHD while there were a total of 12299 children in the Healthy eaters group and 105 cases of ADHD were recorded. Calculate a suitable measure of association to explore if there is a link between poor diet and ADHD. Please provide only the final answer with two decimals and use of brackets is essential. QUESTION 12 A unit coordinator conducted a case control study to explore if there was association between taking part in the end of semester 'Evaluate' survey (exposure) measured as yes/no, and overall performance measured as pass/fail (outcome). As per alternative hypothesis those who passed were more likely to have done their evaluate contribution than those who did not pass. A total of 2525 cases were chosen (those who passed) and a total of 2446 controls were chosen who did not pass. It was found that 905 cases had done the evaluate while only 309 controls took part in evaluate. Calculate a measure of association, suitable for this study design, to establish if there is infact a link between evaluate and pass grade). Though a 2x2 table will really help you to begin with, please provide only the final answer with two decimals and use of brackets is essential.
