Once you have the search results you can start to reduce the number of studies by reviewing the titles/abstracts and then obtain full text for the remainder of papers. You should definitely have more than one content expert check the eligibility of the studies based on your predetermined inclusion/exclusion criteria. You might also want to consider developing a strategy to resolve any possible disagreements and should keep a log of excluded studies with why you have decided to exclude them. It is important at this point to appraise the quality of the studies either using simple checklist and/or quality scales.
