A researcher wants to assess whether childhood secondhand smoke exposure can be associated with lung cancer disease. 500 adults participated in this study, and they were divided into two groups based on their childhood secondhand smoke exposure status. The participants were also requested to report whether they were diagnosed with lung cancer or not. The incidence rate of lung cancer was then compared between the exposure and unexposure groups. What type of study design is it? A) A case series B) A retrospective cohort study C) A prospective cohort study D) A case-control study

Step 1
The study involves dividing participants into two groups based on their exposure status to secondhand smoke during childhood. Then, it assesses the incidence of lung cancer in both groups. This setup involves following up with participants to see who develops a Show more…

Suppose we performed a case-control study examining whether secondhand smoke exposure as a child was associated with lung cancer. We ask 250 lung cancer patients and 250 controls whether they ever had secondhand smoke exposure as a child. We collected the following data. Calculate and interpret the odds ratio. Childhood Secondhand Smoke Exposure Case Control yes 150 50 no 100 200

A survey was conducted to study the relationship between lung disease and air pollution. Four areas were chosen for the survey. two cities frequently plagued with smog and two nonurban areas in states that possessed low air-pollution counts. Only adult permanent residents of the area were included in the study. Random samples of 400 adult permanent residents from each area gave the results listed in the accompanying table. a. Do the data provide sufficient evidence to indicate a difference in the proportions with lung disease for the four locations? b. Should cigarette smokers have been excluded from the samples? How would this affect inferences drawn from the data?

In a cohort study of smoking and lung cancer, the incidence of lung cancer among smokers was found to be 9/1,000 and the incidence among nonsmokers was 1/1,000. From another source we know that 45% of the total population were smokers The incidence of lung cancer attributable to smoking in the total population is: The proportion of the risk in the total population that is attributable to smoking is:
