I recently contributed in a workshop about systematic review. This kind of review, which is somehow similar to the traditional literature reviews, focuses on a specific topic to identify, evaluate, select and synthesize all high quality and relevant research evidence relevant to that topic. In systematic review we should define the inclusion and exclusion criteria to map the area according to these items. Some people think this kind of review is only useful in the medical sciences. However, I believe this is useful for any scientific field. In future posts I will write more about the advantages and disadvantages of it and how we can compare it with traditional reviews.
