An umbrella review allows the findings of reviews relevant to a review question to be compared and contrasted. An umbrella review’s most characteristic feature is that this type of evidence synthesis only considers for inclusion the highest level of evidence, namely other systematic reviews and meta-analyses.

What is an umbrella literature review?
Umbrella reviews are reviews of previously published systematic reviews or meta-analyses. Therefore, they represent one of the highest levels of evidence synthesis currently available, and are becoming increasingly influential in biomedical literature.
Is an umbrella review the same as a systematic review?
In medical research, an umbrella review is a review of systematic reviews or meta-analyses. They may also be called overviews of reviews, reviews of reviews, summaries of systematic reviews, or syntheses of reviews. Umbrella reviews are among the highest levels of evidence currently available in medicine.

What is a scoping review level of evidence?
Scoping Reviews: a scoping review determines the size and nature of the evidence base for a particular topic area, which can in turn be used to identify gaps in the literature and make recommendations for future primary research.
What is Umbrella research?

How do you write an umbrella review protocol?
The points are: ensure that the umbrella review is really needed, prespecify the protocol, clearly define the variables of interest, estimate a common effect size, report the heterogeneity and potential biases, perform a stratification of the evidence, conduct sensitivity analyses, report transparent results, use
What level of evidence is a Cochrane review?
Cochrane has adopted the GRADE approach (Grading of Recommendations Assessment, Development and Evaluation) for assessing certainty (or quality) of a body of evidence. The GRADE approach specifies four levels of the certainty for a body of evidence for a given outcome: high, moderate, low and very low.

|---|---|
| Level V | Evidence from systematic reviews of descriptive and qualitative studies (meta-synthesis). |
| Level VI | Evidence from a single descriptive or qualitative study. |
| Level VII | Evidence from the opinion of authorities and/or reports of expert committees. |

What type of study is a scoping review?
Scoping reviews (also known as mapping reviews) are exploratory research projects that systematically map the literature on a topic by identifying key concepts, theories and sources of evidence that inform practice in the field.
What is umbrella protocol?
