A minimum of 2 reviewers must read and separately make a decision on each abstract. Each reviewer must individually, without influence of another, decide if each abstract should be included (Yes), excluded (No), or needs further examination of full-text or discussion (Maybe).Using a software/website specific for this purpose is helpful. Some are freely available online, like Rayyan. Others are paid software, like Covidence. Covidence gives each individual one free review.
The decisions of the paired reviewers should be compared when completed.
During the screening process on Rayyan, blinding is on. This means each reviewer can only see their own decisions, and cannot view the decisions made by other reviewers. Before the process of resolving conflicts can be started, blinding needs to be switched off, which can only be done by the review owner (the person who originally created the review in Rayyan).
Once blinding has been switched off, reviewers are able to see those articles where there is currently disagreement by selecting "Conflicts" in the left hand bar. As agreement is reached on each article, it is then a simple matter for the relevant reviewer to change their opinion.
