After all the included databases have been searched and all the results have been stored in a reference management tool such as EndNote, duplicate references need to be removed. Then these references can be either exported to a screening tool for the reviewers to screen or stay in EndNote for screening. There are usually three reviewers to perform screening. If reviewer 1 does not agree with reviewer 2 on a particular reference, then the reviewer 3 will join in to resolve the conflict.
