CPH 672 Exam 2 Questions with 100% Verified Answers
UPDATED!!!
A cluster-randomized trial (similar to the one you read about a
surgeon-delivered counseling intervention) was applied to
reduce alcohol consumption among low-income adults
experiencing alcohol-induced cardiomyopathy. Clusters were
alcohol rehab centers in low-income neighborhoods of three US
cities. In each city 6 clusters were selected and randomly
assigned to either the intervention or comparison condition.
The primary outcome was biologically assessed abstinence from
alcohol. The outcomes were assessed immediately after a 6-
week group-based intervention occurred. Outcomes were also
assessed 30 days after the end of the 6-week program. Of the
options shown below, what is the weak point here?
Which one criterion from Table 1 is needed before you can
make an informed judgment about the value of the comparison
clusters? - ANSWER Whether the comparison clusters differed
from the intervention clusters at baseline

The prospective period of assessment is far too short
A Cochrane Review of best practices for promoting adherence
to hypertension medication features a 10-year study of people
completing an online course called "manage your lifelines." The
course was first given to a group of 90 people with
hypertension; than later given to a second group of 92 people
with hypertension. The design used for this study was most
likely: - ANSWER an RCT with a waitlist control condition
A Cochrane Review of best practices for promoting adherence
to hypertension medication features a 10-year study of people
prescribed medication to control control hypertension. 500
people were enrolled and an intervention was not provided.
The design used for this study was most likely: - ANSWER a
prospective cohort design

A health services study finds evidence that people who have
had a "trusted primary care provider" for at least ten years are
significantly less likely to be obese (OR = .72). Knowing nothing
else, this has to be a: - ANSWER a case-control study
A modeling paper examines the lifetime costs of smoking, in
terms of paying for tobacco. The conclusion reads, "The average
lifetime costs incurred by a typical American were estimated at
$27,450. This value ranged as high as $34,300 for people who
began use in their teens, and as low as $19,720 for people who
were not addicted to nicotine until reaching their late
twenties."
As you read more closely in this paper you discovery this: "The
estimate of $27,450 is one that is moderately reliable
($24,900/$29,100)."
What are these numbers in parenthesis all about? - ANSWER
these are uncertainty levels; the authors are accounting for
uncontrolled variation in the model
