Question
Researchers at an epidemiology clinic have conducted a study investigating the relationship between exposure to asbestos and lung cancer. The following table represents the findings from the study after a follow-up period of 10 years.
Calculate the proportion of lung cancer cases in the exposed
and unexposed
Lung Cancer No Lung Cancer Total Asbestos Exposure + 153 201 354 Asbestos Exposure - 23 664 687 Total 176 865 1041Calculate the proportion of lung cancer cases in the exposed
and unexposed
Explanation / Answer
Proportion of lung cancer in exposed cases = 153/354 = 0.4322
Proportion of no lung cancer in exposed cases = 23/687 = 0.0335
