How do you complete a meta-analysis?
We have broken the process of meta-analysis into six steps: (1) do a literature search; (2) decide on some inclusion criteria and apply them; (3) calculate effect sizes for each study to be included; (4) do the basic meta-analysis; (5) consider doing some more advanced analysis such as publication bias analysis and …
How many studies should be included in a meta-analysis?

This paper provides an introduction to when and how to conduct a meta-analysis. Several practical questions, such as advantages of meta-analysis over conventional narrative review and the …
Can a meta-analysis be an exploratory publication?
In this case, an exploratory meta-analysis can provide a plausible estimate of effect that can be tested in subsequent studies ( 33, 34 ). This type of publication type has many potential limitations that should be appreciated by all readers.
How are pooled results presented in a meta-analysis?
Graphically, the pooled result is often presented as a diamond at the bottom of the plot. When performing a meta-analysis, a review team usually combines aggregate-level data reported in each primary study (point and variance estimate of the summary measure).
What is the difference between a meta-analysis and a systematic review?
A systematic review attempts to gather all available empirical research by using clearly defined, systematic methods to obtain answers to a specific question. A meta-analysis is the statistical process of analyzing and combining results from several similar studies.
