Pick your study designs

 

What types of studies will help you answer your question? Remember, you want to know:

Ideally, you’d only include studies at the top of the hierarchy of evidence. Of those, which fit the needs of your systematic review?

Randomized Controlled Trials (RCTs): YES

Cohort Studies: YES

These could be useful for information about the long-term safety of each kidney failure intervention.

Case-control studies: Probably not

You’re not looking for the cause of kidney failure. You’re trying to compare two types of treatment.
