An epidemiologist found five cases of "big toe cancer" in the Yukon Territory. Because there were only a few cases, the epidemiologist decided to conduct a matched case-control study to determine whether shoe size larger than 9 is a risk factor for big toe cancer. Cases were individually matched to one control for daily activity, history of athlete's foot, and history of ingrown toenails. The following data were gathered:

Shoe size > 9

Pair Case Control

1 Yes No

2 No No

3 No Yes

4 Yes Yes

5 No Yes

Compute the proper measure of association.

Interpret your results.

If you were to investigate a rare cancer in Lynchburg, where might you look for data?

What would be necessary legally and ethically to be able to utilize this data set (s) ?

Moshe Roberts · Answer 1

Step-by-step explanation:

Given that:

An epidemiologist found five cases of "big toe cancer" in the Yukon Territory.

Therefore, shoe size > 9

1) From the required data given below

Case Control Total

Yes 2 (a) 3 (b) 5

No 3 (c) 2 (d) 5

Total 5 5 10

∴ odds ratio = ad/bc

= 4/9

=0.444

2) From the less than 1.0 mean that the odds of cancer among case is lower than the odds of cancer among controls
