RR = 1 means that the treatment does not affect the outcome.
True
False
It indicates a negative effect on the outcome
It suggests the treatment enhances the outcome
The correct answer is: True
If RR = 1, it indicates that the treatment does not have an effect on the outcome. This means that there is no change or difference in the outcome between the treatment group and the control group. Option B is the correct answer because it aligns with the definition of RR = 1. Options C and D are incorrect because they both suggest that the treatment has an effect on the outcome, while the definition of RR = 1 states that there is no effect. It is important to carefully read and understand the question to choose the correct answer.
