At a party of 100 people, 20 people later became ill. 15 of the 100 people ate the pork, 8 of which matched the case definition for the illness. What is the odds ratio for the pork? Interpret your result.
The odds ratio for the pork is 6.95, which indicates that those who ate the pork are 6.95 times more likely to contract the illness that those who did not eat the pork. This leads us to believe that pork is likely the cause of illness, although we cannot be sure until lab verification.

we cannot conclude that those who ate the pork are 6.95 times more likely to contract the illness based on the odds ratio. We can only conclude that there is a high degree of association between the pork and the illness. Any assessment of the risks between the two groups (or cohorts, if you prefer) would require a relative risk calculation.
Your turn!
