Case-Control studies are valuable when a disease is rare.
Group of answer choices
True
False
Calculate the odds ratio for the following data
| Has CHD | No CHD | Total | |
| Smoker | 20 | 25 | 45 |
| Non-Smoker | 80 | 175 | 255 |
| Total | 100 | 200 |
300 |
What conclusion can you make about the odds ratio you calculated?
Group of answer choices
Smoking is related to CHD because the odds ratio is greater than 1
Smoking is related to CHD because the odds ratio is greater than zero
Smoking is related to CHD because the odds ratio is positive

Because we are observing new cases of disease in a cohort study, what kind of relationship may we establish? Group of answer choices Confounding Temporal Positive Negative Why might there be uncertainty with the association between an exposure and disease in an observational study? Group of answer choices The association may be due to the factors that led people to be exposed (e.g. confounders) rather than the exposure itself. Case-control studies are more valid, so they should be the standard...

Which of the following is not true? Group of answer choices The dividend growth model seeks to estimate the current market value of a stock by calculating the total future value of the future dividend payments. The dividend growth model cannot be used to estimate the current market value of stocks of firms that don’t issue any dividends. There are ways other than the dividend growth model to conduct stock valuation, including multiplying a benchmark Price-to-Earnings ratio with earnings per...

Lung Cancer & Smoking Case Study A causal relationship between cigarette smoking and lung cancer was first suspected in the 1920s on the basis of clinical observations. To test this apparent association, numerous epidemiologic studies were undertaken between 1930 and 1960. Two studies were conducted by Richard Doll and Austin Bradford Hill in Great Britain The first was a case-control study begun in 1947 comparing the smoking habits of lung cancer patients with the smoking habits of other patients. The...

The data of a major referral hospital showed that most patients with ischemic heart disease (IHD) were black American. Based on this, it was concluded that black Americans are at higher risk of IHD compared to other community groups. How would you describe the conclusion? A. Correct, because risk factors for IHD are more common in black African American. B. Incorrect, because no test of statistical significance has been made C. Incorrect, because prevalence is used instead of incidence D....
