Screening is a time-consuming two-part process to determine which citations meet the team's eligibility criteria and should be included in the review. To reduce bias, a minimum of two reviewers typically screen the search results and resolve areas of disagreement by consensus or a third tie-breaker team member who is a content expert. A number of online tools, such as Covidence, exist to facilitate the process.
1) Title/Abstract Screening
2) Full Text Screening
