artificial sweeteners in the past, while 1707 had never used
artificial sweeteners. Of the controls, 855 had used sweeteners and
2145 had not.

c. Which measure of association/comparison should we use to
assess the strength of the relationship between the exposure and
disease?
d. Calculate the correct measure and show your work.
e. How do we interpret this effect estimate?
