A randomized trial of 9361 persons was performed to assess the most appropriate targets for systolic
blood pressure to reduce cardiovascular morbidity and mortality in patients without diabetes. The
results of the study show that targeting a systolic blood pressure of less than 120 mm Hg, as compared
with less than 140 mm Hg, results in lower rates of fatal and nonfatal cardiovascular events and death.
However, based on these results, conclusions cannot be drawn for certain populations - such as persons
with diabetes. Regarding these populations, this study can be said to have: A. High Internal Validity B.
Poor Generalizability C. High External Validity D. Reduced Study Power - ANSWERSB
A research team is studying the relationship of SIDS, sudden infant death syndrome, and exposure to
cigarette smoke. To do this they look through a government data base to compare death certificates that

who smoked in the household. This is an example of what type of study?
Possible answer #1: Ecological study
Possible answer #2: Observational study
Possible answer #3: Interventional study
Possible answer #4: Case-crossover study - ANSWERS#2

between Slurpee sales and outside temperature. Here obtained the following data: Slurpee sales ($)
Temperature (F) 1000 100 700 75 525 55 150 23 If Dr. M was to calculate a correlation coefficient for this
set of data, he would most likely expect this value to be closest to: Possible answer

inconvenient. This type of health intervention is considered:
,Possible answer #1: Community
Possible answer #2: Educational
Possible answer #3: Rehabilitation
Possible answer #4: Genetic - ANSWERS1
A study was done around what used to be a nuclear facility to see if there was a cluster of cancer in small
town. Which of the following would MOST increase the likelihood of this being a true cluster, rather than
a coincidence?
Possible answer #1: The suspected cluster has an increased incidence of lung cancer in 50-70 year old
males compared to surrounding communities
Possible answer #2: The suspected cluster has an increased proportion of melanoma in 40-60 years old
females compared to surrounding communities
Possible answer #3: The suspected cluster has a reduced life expectancy by 10 years compared to the
national average
Possible answer #4: The suspected cluster has a greater incidence of renal cell carcinoma in children
compared to the national average - ANSWERS4
In the 2019 VSD study, cases for spontaneous abortions were placed into groups based on the date of
conception and timing of flu vaccination during or before their pregnancy. The researchers selected
controls for this study with similar characteristics to the case subjects. What is this an example of?
Possible answer #1: Matching
Possible answer #2: RCTs
Possible answer #3: Confounding
Possible answer #4: - ANSWERS1
A medical student suspects that there is a link between Alzheimer's disease and exercise such that
exercise reduces the risk of developing Alzheimer's disease. She sets up a research project in which she
will follow a set of patients who are currently 50 years old and all have similar risk factors. These patients
will log their weekly hours of exercise including what kind of exercise was performed. The student plans
to follow these patients for 20 years and evaluate their potential development of Alzheimer's disease.
Which of the following is true about her study design?
Possible answer #1: It utilizes the hypothesis-generating approach to study designs.
Possible answer #2: It is a poor design because it utilizes an implausible hypothesis.
, Possible answer #3: It utilizes the hypothesis-driven approach to study designs.
Possible answer #4: It utilizes methods that will not need to take into account the history of - ANSWERS3

Genome-wide association studies examine single nucleotide polymorphisms (SNPs) that occur more
frequently in individuals with a particular disease than those without it. These studies often find
associations between gene variants and diseases that cannot be replicated in other studies. Which of the
following is a possible reason that these findings are not always replicable?
A. Tag SNPs are responsible for the cause of disease being studied, and are therefore hard to study
B. The diseases being studied do not follow heritability of Mendelian genetics, and therefore cannot be
assessed by GWAS
C. Multiple gene variants contribute to the cause of disease in complex ways
D. The findings of GWAS are easily replicable - ANSWERSC
Through its National Notifiable Disease Surveillance System (NNDSS), the Center for Disease Control and
Prevention can track the both the incidence and prevalence of measles in the United States. In recent
years, there has been an increase in the number of MMR vaccinations given for measles. However, many
parents are worried about the safety of this vaccine and the potential for adverse effects. Of the 453,000
people who received an MMR vaccination in 2019, only 27 individuals experienced encephalopathy. Of
the 247,000 who did not receive the MMR vaccination, 7 individuals experienced encephalopathy.
Calculate the population attributable risk. To perform your calculation correctly, please note that the
incidence of encephalopathy in the exposed is 27/453,000, in the unexposed is 7/247,000, and in the
total population is 34/700,000.
