Example 2: We often think food poisoning is a good scenario to consider when interpreting ORs: Imagine a group of 20 friends went out to the restaurant the next day a 7 were ill. They suspect that it may have been something they ate, maybe the fish casserole here are the numbers: Cases Controls (ill) (not ill) Total Exposed (ate fish) 5 3 8 Unexposed (didn't eat fish) 2 10 12 7 13 20 find i. Odds of exposure in cases ii. Odds of exposure in controls iii. Odds Ratio of cases to controls and comment Hints: (0R=8.3 Comment: In the example above, we can conclude that those who ate the fish casserole (exposure) were 8.3 times more likely (OR = 8.3) to be ill (outcome), compared to those who did not eat the fish casserole
