In line with the objectives of a JBI Umbrella Review to present an accurate and informative overview of the findings of research syntheses that inform a broad topic or question, all JBI Umbrella Reviews should conclude the results section of the report with a final and easily interpretable table that presents the overall “Summary of Evidence”.
For quantitative findings, a final table should be presented that names the intervention, identifies the included research synthesis and provides a simple, visual indication of the results. Visual indication should follow a simple “stop-light” indicator, where green indicates the intervention is beneficial (effective), amber that there is no difference in the investigated comparison, and red that the results suggest the intervention is detrimental or less effective than the comparator. Actual details and effect estimates are presented in the findings of the review (see above). Table 10.4 presents an example for “aggressive behavior”. Further outcomes reported in an Umbrella Review could be added in columns to the right. Where a study does not report on an outcome, the indicator square should be left blank.

Similarly, Umbrella Reviews that include qualitative syntheses should also conclude the results section with a clear summary of the overall findings of the included research syntheses.
In the final summary table, the key synthesized findings should be presented for the reader; for other contextual details the main findings can be referred to (see above). Similar to a summary presentation of qualitative findings, visual indicators of the finding should be included where possible. In the example provided in Table 10.5, those perspectives (see phenomenon) that are beneficial or facilitative are highlighted in green, while those that are inhibitory are highlighted in red.
