Two types of medical devices used for knee replacement are being studied to see if the type of knee replacement used affects the rate of infection for a specific bacterial infection. The infection rate for a specific bacterial infection after surgery for device A is 0.0043. The rate for the same bacterial infection is 0.0121 for device B. How does the risk of developing the bacterial infection in individuals using device B compare to the risk of developing the bacterial infection in individuals using device A? Individuals using device A are 2.814 times more likely to develop the bacterial infection of interest than individuals using device B. Individuals using device B are 2.814 times more likely to develop the bacterial infection of interest than individuals using device A. Individuals using device A are 1.35 times more likely to develop the bacterial infection of interest than individuals using device B. Individual using device B are 1.35 times more likely to develop the bacterial infection of interest that individuals using device B.
