Umbrella review

In medical research, an umbrella review is a review of systematic reviews or meta-analyses.[1][2][3] They may also be called overviews of reviews, reviews of reviews, summaries of systematic reviews, or syntheses of reviews.[1] Umbrella reviews are among the highest levels of evidence currently available in medicine.[2]

By summarizing information from multiple overview articles, umbrella reviews make it easier to review the evidence and allow for comparison of results between each of the individual reviews.[1] Umbrella reviews may address a broader question than a typical review, such as discussing multiple different treatment comparisons instead of only one.[1][3] They are especially useful for developing guidelines and clinical practice, and when comparing competing interventions.[1][3]
