A systematic search and review combines strengths of critical review with a comprehensive search process and typically addresses broad questions to produce ‘best evidence synthesis’’ . This type of review "often incorporates multiple study types rather than focusing on a single preferred study design". A limitation of this method is the lack of explicit inclusion and exclusion criteria and a clearly defined process of synthesis (Grant & Booth, 2009)
