After screening, it is recommended to report the results of the process using a flow diagram.
PRISMA (Preferred Reporting Items for Systematic Reviews and Meta Analyses) is a commonly used flow-diagram to illustrate the screening process (Literati et al., 2009). Although it is typically the standard reporting tool for systematic reviews and meta-analyses, it may also be used for other types of reviews.
Examples and templates of PRISMA flow diagrams can be found here. PRISMA also has a procedural checklist pertaining to systematic reviews and meta-analyses.
