Cоnsider а hypоtheticаl cоhort study on the effect of smoking on the risk of Alzheimer's Diseаse (AD) among a total of 2000 adults. Smoking was assessed based on a single question assessing lifetime history of smoking. AD was assessed using the Mini–Mental State Examination (MMSE) where a score of 12 or less was considered positive for AD. Round your final answer up to the nearest one-tenth (x.x). Some results of this study are presented in the following table: 1. The exposure variable was [1] (response options: smoking, AD) 2. The outcome variable was [2] (response options: smoking, AD) 3. The cumulative Incidence of AD in the total sample was [3] percent (no need to write the symbol "%" or the words "per 100", just the number). 4. The cumulative Incidence of AD among smokers was [4] percent. 5. The cumulative Incidence of AD among non-smokers was [5] percent. 6. The risk of AD is [6] times as high among smokers as compared to non-smokers. 7. There are about [7] more individuals diagnosed with AD among every 100 smokers, than among non-smokers. The researchers considered that age might confound the association between AD and smoking. The following tables show the association between AD and smoking across two levels of age. 8. The proportion of smokers among individuals 80 to 99 years old was [8] percent. (only enter the number when asked for percentage) 9. The proportion of smokers among individuals 45 to 79 years old was [9] percent. 10. The rate of smoking was [10] times higher among individuals 80 to 99 years old than among individuals 45 to 79 years old. 11. Among non-smokers, the cumulative incidence of AD among individuals 80 to 99 years old was [11] percent. 12. Among non-smokers, the cumulative incidence of AD among individuals 45 to 79 years old was [12] percent. 13. Among non-smokers, the risk of AD is [13] times higher among individuals 80 to 99 years than among individuals 45 to 79 years old. 14. Among non-smokers, there are about [14] more individuals diagnosed with AD among every 100 individuals 80 to 99 years , than among individuals 45 to 79 years old. 15. Based on the relative estimates, age [15] (response options: was, was not) a potential confounder of the association between smoking and AD. 16. Among individuals 80 to 99 years old, the cumulative incidence of AD among smokers was [16] percent. 17. Among individuals 80 to 99 years old, the cumulative Incidence of AD among non-smokers was [17] percent. 18. Among individuals 80 to 99 years old, the risk of AD is [18] times higher among smokers compared to non-smokers. 19. Among individuals 80 to 99 years old, there are about [19] more individuals diagnosed with AD among every 100 smoker, than among non-smokers. 20. Among individuals 45 to 79 years old, the cumulative incidence of AD among smokers was [20] percent. 21. Among individuals 45 to 79 years old, the cumulative incidence of AD among non-smokers was [21] percent. 22. Among individuals 45 to 79 years old, the risk of AD is [22] times higher among smokers compared to non-smokers. 23. Among individuals 45 to 79 years old, there are about [23] more individuals diagnosed with AD among every 100 smoker, than among non-smokers. 24. Based on the relative estimates, age [24] (response options: was, was not) is/ an actual confounder of the association between smoking and AD.
