Question 1
The independent/exposure variable is displayed on the x-axis in most
graphs.
True
False
pts
Question 2
The following table is from a large cohort study about the effects of
physical activity and body mass index on cardiovascular, cancer and all-
cause mortality among middle-aged Finnish men and women. Calculate
the percentage of risk reduction of cancer mortality for women with
high physical activity levels using the hazard ratios listed under
Model 1. In other words, how much lower (percentage) is the risk of
dying from cancer within the follow-up period for middle-aged
Finnish women who engage in high physical activity levels
compared to the reference category? Note: The numbers you need to
calculate the percentage of risk reduction can be found within the red box.
Hazard ratios are shown in that column, but they can be interpreted and
used the same way as risk ratios (relative risk), at least for our purposes.
The numbers that you see in parentheses represent the 95% confidence

Question 3
How strong is the effect of exercise on insulin sensitivity when the
last exercise session was more than 72 hours ago? Find the effect
size and enter it here with two decimals and no units. The answer to
this question can be found in the abstract of the study.

Question 4
Incidence refers to the number of new cases within a given time period.
True
False
pts
Question 5
The following table is from a large cohort study about the effects of
physical activity and body mass index on cardiovascular, cancer and all-
cause mortality among middle-aged Finnish men and women. Calculate
the percentage of risk reduction of total mortality (all-cause
mortality) for men with high physical activity levels using the hazard
ratios listed under Model 1. In other words, how much lower
(percentage) is the risk of dying from any cause within the follow-up
period for middle-aged Finnish men who engage in high physical
activity levels compared to the reference category? Note: The
numbers you need to calculate the percentage of risk reduction can be
found within the red box. Hazard ratios are shown in that column, but they
can be interpreted and used the same way as risk ratios (relative risk), at
least for our purposes. The numbers that you see in parentheses

Question 6
The meta-analysis referenced below (Oberlin et al., 2017) sought to
determine the effect of exercise on cognitive function in people who had a
stroke. Based on the 95% confidence interval (95% CI) for the overall
effect (ES total) of exercise on cognitive performance, is the effect of
exercise on cognitive performance statistically significant?
