Results of knowledge syntheses may be presented in numerous ways. The screening process may be described in the text and/or presented as a flow chart. Characteristics of included studies are generally presented by study in tabular form and/or synthesized textually. The results of risk of bias assessments may also be presented in a table or in text and sufficient detail should be provided to allow the end user to be able to determine the potential threats to validity. The PRISMA checklist is a helpful tool for presenting the result for the risk of bias.
Quantitative data should be presented as summary data and as effect estimates with confidence intervals for each estimate possible. Qualitative data may also be presented visually as, for example, a conceptual framework.
