Question

Use the TUA library to find an article describing a randomised control trial in an area of public health that you find interesting, and summarise it briefly. What are the benefits and limitations of using an RCT in this specific context (and I'm interested in your opinions, not just the statements from the researchers!)? Could any other study designs have been used to explore the same research question?

This question is related to the public health and there is not public health option so I selected nursing
