Cancer survivors who have influenza flu are at particularly

Cancer survivors who have influenza (flu) are at particularly high risk for complications. Thus, clinicians recommend influenza vaccination for all cancer survivors. A research team in Korea used cross-sectional data from the Korean National Health and Nutrition Examination Survey (KNHANES) to investigate vaccination coverage among cancer survivors in Korea. The table below is adapted from the researchers\' findings for adults below the age of 65. Use the table to answer the questions that follow.

What is the prevalence of vaccination among cancer survivors?

What is the prevalence of vaccination among individual with no cancer history?

What measure of association is used for this type of study design?

Calculate the measure of association for the association between cancer survivorship and influenza vaccination.

which calculation provides the most useful information for drawing conclusions? Why?

Solution

Prevalance of vaccination among cancer survivors = (227 )/(227+406+6028+20294) = 0.0084

Prevalance of vaccination among individual with no cancer history= (6028 )/(227+406+6028+20294)

= 0.2236

Measure of association : Difference in proportion.
