Types of Clinical Questions Clinical questions may be categorized as either background or foreground. Why is this important? Determining the type of question will help you to select the best resource to consult for your answer.

A statistical technique that summarizes the results of several studies in a single weighted estimate, in which more weight is given to results of studies with more events and sometimes to studies of higher quality.

It can, but need not, involve meta-analysis. In Clinical Evidence, the term systematic review refers to a systematic review of RCTs unless specified otherwise.

This design allows assessment of the relative effects of interventions.learning effectiveness of the two cases.
