1, case-control study design will be most appropriate for this study.
2, case-control study is a type of observational study between two groups (smoking and nonsmoking) that differ the outcome needed to be identified and compared. it helps to determine the exposure associated with the outcome (lung cancer). a case-control study is a retrospective that finds the outcome by investigating the exposure group.
3, the strength of this study, it is efficient for rare cases of diseases. lung cancer with long latency periods between exposure and disease identification. this study design is low cost and less time consuming, their data is hard to obtain and low-risk identification, this study includes a dynamic population. limitation of this study design it causes subject to selection bias, there will be rare exposure for lung cancer with signs and symptoms, it causes subject to observation bias. this study design does not allow calculation of incidence that causes absolute risk.

What is the attributable risk of dying of lung cancer for smokers versus non-smokers?
It is known that smoking is also a risk factor for lung cancer and other diseases. Studies have shown that the death rate per 100,000 for lung cancer is 7 among non-smokers and 71 among smokers. The death rate per 100,000 for coronary thrombosis is 422 among non-smokers and 599 among smokers. The prevalence of smoking in the population is 55%.What is the attributable risk of dying of lung cancer for smokers versus non-smokers?What is the interpretation of the attributable...

In a study comparing two treatment options for lung cancer, men with stage 2 lung cancer are randomized into two groups to receive either a new immunotherapy or traditional chemotherapy. These men are then followed for 1 year to determine if there are any differences in lung cancer survival rate into two groups. What kind of study is this? EPIDEMILOLOGY

A retrospective study conducted in Japan in 1975 investigated the relationship between Smoking and Lung Cancer. After the study was done, the 2000 people in the sample were classified by whether the had died from Lung Cancer (LC) or not (NLC) and by whether they had been smokers (S) or non-smokers (NS) during their lifetimes. The final table produced from the sample looked like this: S NS TOTAL LC 350 150 500 NLC 624 876 1500 TOTAL 974 1026 2000...

Explain the result of aspirating food and explain why the problem may be difficult to identify. 4. Explain how obstruction develops in an asthmatic patient following exposure to an inhaled allergen. 5. Compare the effects of partial and total obstruction of the airway on ventilation and on oxygen levels in the blood.

For studying the average pulse rates between three groups of people: smokers, ex-smokers, and non-smokers, three independent random samples of male subjects were selected from the three populations. The data, sitting pulse rates per minute measured in the morning, is listed below. Smokers: 88, 82, 80, 75 Ex-smokers: 70, 72, 73, 72 Non-smokers: 68, 70, 70, 75 Which of the followings are correct when one performed One-way ANOVA F-test for testing whether the difference in means of the sampled population...

Our project explains the effect of cox-2 inhibition in non-small lung cancer, breast cancer, and lymphoma cell lines. the question that might be asked is why did we choose to inhibit cox-2 gene despite other genes that might be present in a cancer cell line? what is the answer for that?

1. You are studying a particular type of lung cancer, small-cell lung carcinoma. You are interested on driver mutations of this cancer, that is mutations that provide strong selection advantage and thus have strong potential in initiating tumorigenesis. You have access to primary tumor biopsies from patients, and healthy surrounding tissue: how you can best use these tissue samples to identify mutations underlying this particular type of lung cancer? 2. The mutation you isolated has not been characterized before; how...
