Question
Consider the following 'true' and misclassified collected data from a hypothetical case-control study of statin use and Alzheimer's disease. Assume the sensitivity of exposure measurement
Consider the following 'true' and misclassified collected data from a hypothetical case-control study of statin use and Alzheimer's disease. Assume the sensitivity of exposure measurement is 100%.
No misclassification ("Truth")
Alzhemers disease and Statin use =40
No Alzheimers disease and statin use =30
Alzheimers disease and no statin use = 50
No Alzhmeir disease and no statin use = 70
Misclassification
Alzhemers disease and Statin use =45
No Alzheimers disease and statin use =50
Alzheimers disease and no statin use = 45
No Alzhmeir disease and no statin use = 50
a. Calculate the specificity of exposure among cases with Alzheimers
b. Calculate the specificity of exposure among controls without Alzheimers
c. Which of the following correctly describes the type of misclassification:
a.Nondifferential misclassification of disease.
b.Differential misclassification of disease
c.Nondifferential misclassification of exposure
d.Differential misclassification of exposure
