RR = 0.03430/0.02813
RR = 1.21933
b. the odds ratio for the association of alcohol use (exposure) use and cancer by using the following formula
OR = (135/165)/(3800/5700)
OR = 0.8181/0.6667
OR = 1.2270

The study is conducted to investigate the association between chewing tobacco
CASE ONE The study is conducted to investigate the association between chewing tobacco and oral leukoplakia (a precancerous lesion) among currently active professional baseball players in the southeastern United States. A roster of all active players is obtained (n=500). All potential study subjects agree to participate. Each subject has an interview regarding current use of chewing tobacco and has his mouth examined by a dentist. Of the 500 subjects, 125 subjects chew tobacco and 375 do not chew tobacco. Of the...

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...

BACKGROUND & METHODS
The relationship between stress and breast cancer has been
examined in many epidemiological studies, the results of which have
yielded mixed results. One reason for these differences is the use
of different measures of stress. For example, death of a spouse or
close relative is a major acute stressor, whereas stress
experienced in daily life is more moderate and chronic in nature.
As these different types of stress likely have different
physiological and psychological impacts, the observed...

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....
