Meta-analysis is a method of synthesis of quantitative data from multiple independent studies addressing a common research question. An important part of this method involves computing a combined effect size across all of the studies.
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]

A meta-analysis is typically a systematic review using statistical methods to effectively combine the data used on all selected studies to produce a more reliable result. [3] Torraco (2016) [4] describes an integrative literature review. The purpose of an integrative literature review is to generate new knowledge on a topic through the process ...
The area of each square is proportional to the study's weight in the meta-analysis. The overall meta-analysed measure of effect is often represented on the plot as a dashed vertical line. This meta-analysed measure of effect is commonly plotted as a diamond, the lateral points of which indicate confidence intervals for this estimate.
Studies about a specific research question or research topic are often reviewed in the form of higher-level overviews in which results from various studies are integrated, compared, critically analyzed and interpreted. Examples of such works are scientific reviews and meta-analyses. These and related practices face various challenges and are a ...
The software is free for non-profit organizations and is available online. [8] The GRADE approach to assess the certainty in evidence is widely applicable, including to questions about diagnosis, [ 9 ] [ 10 ] prognosis, [ 11 ] [ 12 ] network meta-analysis [ 13 ] and public health.
