Answer:
c. The odds of getting a disease in the exposed versus the odds of getting the disease in the non-exposed
Step-by-step explanation:
Odds ratio (OR) is statistic which quantifies strength of association between the two events, say, A and B.
Odds ratio may be defined as ratio of odds of A in presence of B and odds of A in absence of B, or vice versa.
If the two events are independent, the OR becomes equal to 1.
If OR is greater than 1, then A and B are positively correlated and compared to the absence of B, the presence of B raises the odds of A or vice versa.
If OR is less than 1, it means that A and B are correlated negatively, and presence of the one event reduces odds of other event.
The best state is shown by C. So, C is the answer where A is the event of getting the disease and B is some exposure to something.
