CAT's are a brief evidence-based critical appraisal of one or two relevant studies to answer a clinical question. 

A CAT provides a short and brief review.  However, it is a less rigorous version of a systematic review. It is a single piece of evidence that is summarized and should not be considered a complete representation of the entire body of evidence on a clinical issue.
